Check valve is also called one-way valve or check valve, its function is to prevent the medium in the pipeline from flowing back. The bottom valve of the pump to close the water is also a check valve.

The valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.

Cast iron check valves are divided into three types: lift check valves, swing and lift check valves and butterfly check valves. Lift check valves can be divided into two types: vertical check valves and horizontal check valves. Swing check valves are divided into three types: single-leaf check valve, double-leaf check valve, and multi-leaf check valve. The butterfly check valve is a straight-through check valve. The above-mentioned check valves can be divided into three types in connection form: threaded check valve, flanged check valve, and welded check valve.

The installation of the check valve should pay attention to the following: 1. Do not make the check valve bear weight in the pipeline, and the large check valve should be independently supported so that it is not affected by the pressure generated by the piping system. 2. When installing, pay attention to the direction of medium flow should be consistent with the arrow direction of the valve body. 3. Lifting vertical flap check valve should be installed on the vertical pipeline. 4. Lifting the horizontal flap check valve should be installed on the horizontal pipeline.

Nominal pressure or pressure level of check valve: PN1.0-16.0MPa, ANSICLASS150-900, JIS10-20K Nominal diameter or caliber: DN15～900, NPS1/4～36 Connection method: flange, butt welding, thread, bearing Suitable temperature for plug welding: -196℃～540℃ Valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Different materials are selected, and the check valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.

Use of wafer check valve

The check valve is installed in the pipeline system, and its main function is to prevent the medium from flowing back. The check valve is an automatic valve that depends on the pressure of the medium to open and close. The wafer check valve is suitable for various pipelines with nominal pressure PN1.0MPa~42.0MPa, Class150~25000; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540℃, used to prevent The medium flows back. By selecting different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and uric acid.

The main material of the wafer check valve

There are carbon steel, low-temperature steel, duplex steel (F51/F55), titanium alloy, aluminum bronze, INCONEL, SS304, SS304L, SS316, SS316L, chromium-molybdenum steel, Monel (400/500), 20# alloy, Hastelloy, and other metal materials.

6. Sensitive action and good sealing performance

7. The disc has a short stroke and a small closing impact

8. The overall structure is simple and compact, and the appearance is beautiful

9. Long service life and reliable performance

The role of the check valve in the pump water supply system is to prevent the impact of the high-pressure water backflow on the pump impeller. When the system is running for some reason, when the pump suddenly stops running, the pressure in the pump disappears, and the high-pressure water connected to the outlet of the pump will flow back to the pump in the reverse direction. When the pump outlet is equipped with a check valve, it will be closed immediately to prevent the high-pressure water from flowing back to the pump.

The cast steel check valve is an automatic valve whose main function is to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and release the container medium. Check valves can also be used to supply pipelines for auxiliary systems whose pressure may rise above the system pressure. The main function of the check valve is to prevent the medium in the pipeline from flowing back. The opening and closing parts are opened or closed by themselves by the force of the flowing medium. The check valve is only used in the pipeline where the medium flows in one direction to prevent the medium from returning to prevent accidents. We are a check valve manufacturer.

Difference Between Stainless Steel and Brass Valves

When choosing the correct valves for your project, deciding between stainless steel valves or brass valves is very important. Because of the differences in the materials, one is often better suited for a project than the other. There are several types of valve materials on the market, however this article will focus on a comparison of stainless steel valves and brass valves.

 

Brass Valves

Brass is a copper alloy which means that it is stronger than plastic. This additional strength makes them, though not the most expensive option for valve, more expensive than PVC or plastic valves.

Brass is a mixture of copper and zinc, and occasionally other metals. Because of its nature as a soft metal, it is able to resist corrosion very well as opposed to plastic valves. Brass is also able to absorb and withstand more heat than plastic, making brass valves an optimal choice for at home plumbing systems.

One significant difference between stainless steel and brass valves is that brass valves tend to accept welding better than stainless steel valves. This offers some versatility. However, brass valves do have some drawbacks.

Often times, brass valves contain small amounts of lead. Most of the time brass valves are made up of less than 2% lead, however this causes some skepticism for many. In fact, the FDA does not approve of brass valves being used unless they are certified lead-free. Use discretion when choosing the valve material for your next project.

Stainless Steel Valves

While a more expensive option than brass, steel is a very durable, resilient metal. While brass is a copper alloy, stainless steel is an iron alloy mixed with chromium and nickel.

The nature of the material means that these valves are able to effectively resist leaks. Steel is also able to work in more temperatures than brass and tends to last longer. Stainless steel valves are the best options for high pressure and temperature situations. They are also a great material for corrosion resistance.

One type of stainless steel valve, stainless steel 316, is especially corrosion resistant because it has more nickel and also contains molybdenum. This combination of iron, nickel and molybdenum make the valves especially resistant to chlorides and very useful in marine environments.

The Difference: An Overview

This comparison of stainless steel valves and brass valves has provided us a number of significant differences to consider.

Price: Stainless steel valves are more expensive than brass valves. If both materials will meet the needs of your project and budget is a concern, consider using brass valves to save on money.

FDA Approval: The FDA does not approve of brass valves unless they are certified lead-free, making them a poor choice for use in the food industry. Stainless steel, however, is approved by the FDA for use in the industry.

Welding: Because of its chemical makeup, Brass is much better for welding than stainless steel. In order to use stainless steel for welding, you must often break down its oxide layer.

Corrosion Resistance: Brass is able to withstand corrosion better than plastic. However, stainless steel is still the best in the corrosion resistance department, especially in marine environments.

Consider these factors should when deciding on a valve material for your next project. Always make sure that you conduct in depth research about your industry, needs, and the materials that you are interested in, before choosing a valve for your product. Yuanda provides high-quality Brass Valves and Stainless Steel Valves.

The Evolution Of Butterfly Valves

 

The prototype of a butterfly valve

The original butterfly valve was a simple, poorly closed flap valve. It is usually used as a flow regulator and damper valve in water piping systems. With the application of chemically resistant synthetic rubber on the butterfly valve, the performance of the butterfly valve has been improved. Synthetic rubber has the characteristics of corrosion resistance, erosion resistance, dimensional stability, good resilience, ease to form, low cost, etc., and can be selected according to different requirements for the use of different properties of synthetic rubber to meet the working conditions of the butterfly valve. Therefore, it is widely used to manufacture the lining and resilient seat of a butterfly valve.

 

The development of butterfly valve

 

PTFE

Polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, not easy to aging, low coefficient of friction, easy to shape, dimensional stability, and other characteristics. And it can also be filled and added with appropriate materials to improve its comprehensive performance, to get better strength, the lower friction coefficient of the butterfly valve sealing material, to overcome some of the limitations of synthetic rubber. Therefore, the polymeric materials represented by PTFE and its filler-modified materials are widely used in butterfly valves. Thus, the performance of butterfly valves has been further improved. There are butterfly valves with a wider temperature and pressure range, sealing performance, and longer service life.

 

Metal Sealed Butterfly Valves

To meet the use requirements of industrial applications such as high and low temperature, strong erosion, and long life, metal sealed butterfly valves have been developed greatly in the last decade or so. With the application of high-temperature resistance, low-temperature resistance, strong corrosion-resistance, strong erosion resistance, and high strength alloy materials in butterfly valves, metal sealed butterfly valves have been widely used in industrial fields such as high and low temperature, strong erosion, and long life. The butterfly valve with a large diameter (9750mm), high pressure (2.2kN/cm2), and wide temperature range (-102～606℃) has emerged, thus bringing the technology of the butterfly valve to a whole new level.

 

CAD&CAM

Due to the application of computer-aided design (CAD) and computer-aided manufacturing (CAM) and flexible manufacturing system (FMS) in the valve industry, the design and manufacture of butterfly valves have reached a whole new level. The comprehensive innovation of the valve design calculation method reduces the heavy and repetitive routine design work of professional and technical personnel. So that technical personnel has more energy to improve the technical performance of the product and the research and development of new products. Shorten the cycle, improve labor productivity. Especially in the field of metal sealed butterfly valves, due to the application of CAD/CAM, there is a three-dimensional seal designed by CAD and manufactured by cAM CNC machining. It makes the sealing surface of the valve free from any extrusion, abrasion, and wears during the opening and closing process, thus increasing the sealing and service life of the butterfly valve by orders of magnitude.

What is the Difference Between a Knife Gate Valve and a Gate Valve?

While knife gate valves and gate valves share many similarities – they’re both used in on-off applications, involving slurries and other viscous media – there are some noteworthy design variances to consider when weighing up which type of valve would be best suited for your application. While gate valves and knife gate valves share many similar characteristics, there are some fundamental differences that set them apart.

 

HOW DO KNIFE GATE VALVES WORK?

Knife gate valves perform exactly as the name implies. These types of valves were originally designed for the pulp and paper industry. Stringy pulp would impinge between the wedge and seat of a normal gate valve and prevent flow shut-off. Knife gate valves were designed with a sharp edge to cut through the pulp and seal. With this type of useful attribute, the knife gate valve has become invaluable in applications involving slurry, viscous fluids, and other systems where impingement is an issue.

 

HOW DO GATE VALVES WORK?

Gate valves open by lifting a round or rectangular gate (or wedge) out of the path of the fluid. The sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is needed. They have a flat gate closure that slides in and out or up and down between two parallel plates to open or close the valve. Gate valves are used for shut-off, rather than flow regulation because they only have two settings: on and off.

 

KNIFE GATE VALVE APPLICATIONS

Knife gate valves are advantageous in sludge and slurry applications because their blades cut right through thick liquids easily. They’re generally specified in larger sizes for handling thick flows of heavy oils, light grease, slurry, paper pulp, varnish, and wastewater to name but a few knife gate valve applications.

 

GATE VALVE APPLICATIONS

Gate valves are used in many industrial applications requiring shut-off valves, including the oil and gas industry, pharmaceuticals, manufacturing, and automotive. They can cope in demanding environments, such as high temperature and high-pressure environments. Common gate valve applications include power plants, water treatments, mining, and offshore applications.

 

PROS AND CONS OF GATE AND KNIFE GATE VALVES

The advantages of knife gate valves are that they’re cheap, easy to actuate, and light. One of the most notable disadvantages of knife gate valves is that they’re known to have low-pressure limitations. This makes them less desirable for use in applications that require cleanliness or sanitary conditions.

One of the advantages of gate valves is that pressure drop across a gate valve is very low when it is fully open. They can also be used for bi-directional action and are useful as on-off valves. Gate valves do, however, need a large force to operate and large-sized valves need automatic actuators. They’re not quick to open or close, and take up more space when compared to some other valves. Thermal expansion and shrinking can also lead to unwanted leakage in some gate valves that are exposed to high-temperature fluctuations.

Industrial valves are mechanical devices that open, close, or partially block channels to regulate the flow of liquids or gases in a system. the global industrial valves market size was USD 73 billion in 2021 and is expected to reach USD 90.5 billion by 2026, and is projected to grow at a CAGR of 4.4% during the forecast period. Increasing demand for valves in healthcare and pharmaceutical industries due to the COVID-19 pandemic, the surge in demand for setting up new nuclear power plants and retrofitting existing ones, increasing demand for maintenance of connected networks and monitoring of industrial equipment, growing adoption of automation technologies in process industries, and growing focus on the development of smart cities across the globe are the key drivers of the industrial valves market.

 

There are many industrial valve manufacturers across the globe. They produce various types of industrial stock valves, each with unique features and applications, and it can be challenging to find one that will provide the best results in your particular application. As applications have become more specific and complex, valves have evolved into nine main types to suit different requirements. These nine types cover all industrial applications and services.

 

1. Gate valve

Gate valves are designed to be used as isolation valves. These valves help to control the flow of liquid through the pipeline. In order to start or stop the flow of water or any other type of liquid, these valves are fixed to the pipeline. Gate valves are used for various purposes and are commonly found in homes and commercial centers. Different materials such as stainless steel, cast iron, alloy steel, forged steel, etc. are used to manufacture these valves. Gate valve suppliers classify gate valve types into two main types: parallel and wedge valves.

 

Gate valves are used to stop or start the flow of water. The function of a gate valve includes lifting the round shape of a rectangular gate out of the fluid path. When the gate valve is open, there is nothing to impede the flow because the pipe diameter and the gate have the same opening. The valve size can be determined by this orifice diameter.

 

Advantages

- Gate valves have very low frictional losses

- They can be used in both directions in the circuit

- They provide laminar flow with minimal pressure loss

- Gate valves help save energy and reduce the total cost of ownership

Will have low-pressure drop when fully open and seal tightly

 

Applications

Gate valves are excellent shut-off/open valves for any application. They are suitable for wastewater applications and neutral liquids. Gases with a temperature range between -20°C and 70°C and a maximum pressure of 16 bar can be used with gate valves. Knife gate valves are used for slurry and powder media. 2.

2. Globe valve

Globe valves are one of the most popular types of valves for a variety of applications. These valves are similar to gate valves and use linear motion to throttle the flow. They are used to control the flow in the pipeline and are regulated by the position of the movable disc (or plug) relative to the fixed ring seat. The main advantage of a globe valve is that it does not leak like other valves.

 

A Globe valve consists of baffles that separate the inside of the pipe, which is usually parallel to the length of the pipe. They are named after their spherical body shape, with the two halves of the body separated by an internal baffle. It consists of a removable disc element and a fixed ring seat located inside a roughly spherical body.

 

Stop valves are available in three body designs: Z-body, Y-body, and angle valves, and three designs of valve plates: ball, composite, and plug.

 

Advantages

- Stop valves throttle the flow and have a good full shutoff.

- Shorter opening and closing times.

- Easier surface preparation of the valve body seat.

- They can be used as shut-off check valves.

- They contain positive shutoff

 

Applications

Shutoff valves are suitable for a variety of applications because of their ability to stop, start, and regulate flow. Typically, you will see them used for regulatory capacity, including but not limited to fuel systems, boiler and main steam vents and drains, and cooling water systems.

3. Ball Valves

Ball valves are valves that use a ball to control the flow of material from one opening to the next. These valves work by allowing the orifice to open, block or partially open to regulate the flow of gas/liquid. Ball valves are ideal for use with gases because they provide a better seal. They are very versatile as they support pressures up to 700 bar and temperatures up to 200°C and typically range in size from 0.5 cm to 30 cm. They are simple in construction and easy to operate and maintain.

 

They are designed with special measures to allow only the 90-degree rotation required to open and close the ball valve. These valves are a remarkable industrial choice because they provide a reliable and gas-tight seal in a closed position.

 

Types of industrial ball valves include

CSA gas ball valves: Gas ball valves are a special type of ball valve that requires CSA (Canadian Standards Association) certification for safe use incombustible gas applications. Valves that are CSA certified have undergone rigorous quality testing in accordance with U.S. law and measures established by other independent organizations (UL, ANSI, NSF, etc.).

Express/EzGrip Ball Valves: EzPress and EzGrip ball valves are ergonomically designed to be easily and quickly activated or deactivated in industrial applications. These valve connections are designed to save time and money during installation.

PEX Valves: PEX valves are two-way, full-way, right-angle rotary valves most commonly used to shut off the water supply to plumbing fixtures and other equipment during repair or maintenance service. f-1960, f-1807, and Everloc + are the most common types of sex connections.

PP-R Valves: PP-R valves are designed to be compatible with PP-R piping, which is a straight, rigid, cylindrical pipe used to transfer a variety of fluids in industrial applications. the polypropylene composition of PP-R piping and valves makes them highly resistant to corrosive chemicals and abrasive particles. The system uses hot welding and electrofusion to make socket and butt weld connections.

 

Advantages

- They incorporate a compact and low-maintenance design that requires no lubrication

- Cost-effective among all valves

- The biggest advantage of ball valves is their poor throttling characteristics, which can cause the ball valve seat to be susceptible to erosion.

- They provide leak-proof service.

- They can be opened and closed quickly.

- Ball valves offer multi-way design flexibility.

 

Applications

Ball valves are commonly used in flow systems for ships, fire protection services and in the chlorine manufacturing industry. Ball valve suppliers say these valves can be used in a variety of applications and markets, such as gas processing, transmission and storage, and industry.

4. Butterfly Valves

Butterfly Valves Butterfly valves are designed to regulate flow but have limited control. The butterfly valve can be easily operated by turning the handle 90 degrees. It consists of a metal disc in the valve body positioned perpendicular to the fluid in the closed position. The flow of fluid can be regulated by rotating it in the middle. Butterfly valves are configured for electric, manual or pneumatic operation.

 

Butterfly valve suppliers say these valves are used in a wide range of applications such as water supply, wastewater treatment, fire and gas supply, as well as in the chemical and petroleum industries, fuel handling systems, power generation, etc. These valves can be operated by a handle, gear, or actuator depending on specific needs.

 

Advantages

- Butterfly valves are very precise, which gives them an advantage in industrial applications.

- They are very reliable and require little maintenance.

- They have the ability to throttle the flow.

- They can be installed or removed without dislocating the piping system

 

Applications

Butterfly valves are used in wastewater treatment plants, power plants and processing plants for shut-off regulation and isolation services, and are particularly popular in oversized diameter pipelines.

Also used in pharmaceutical, chemical and food processing

They are used for corrosive fluids at low temperatures and pressures.

5. Check Valves

Check Valves Check valves are also known as non-return valves (NRVs). They allow liquid to flow in one direction only and prevent the medium from flowing back in the opposite direction. The purpose of a check valve is to prevent process reversal in a system, which could damage equipment or disrupt the process.

 

They are typically used to protect pumps in liquid applications or compressors in gas systems where backflow may cause the pump or compressor to shut down. The basic design of check valves reduces backflow in the line.

 

Because of their simpler design, they can operate without human interaction and automation. They rely on the flow rate of the fluid to open and close. The higher the flow rate, the more the valve opens until it reaches its maximum fully open position.

 

Types of check valves include

Lift check valves: With lift check valves, the ball or piston opens at a specified pressure to allow fluid flow. A decrease in pressure will force the piston or ball into the seat, which closes the valve and prevents backflow.

Swing check valves: Swing check valves rely on an articulating disc that swings away from the seat to allow forward flow. If the upstream flow is stopped, the valve flap returns to the seat to prevent backflow.

Butterfly Check Valves: Butterfly check valves consist of two semi-circular gates hinged together. Forward flow pushes the gate open, while reverse flow retracts them.

 

Advantages

Simple design.

Effective in preventing backflow.

Can be used as a backup system.

 

Applications

Check valves are used in applications where backflow prevention is required, such as pumps and compressors. Check valves are commonly used for feed pumps in steam boilers. Check valves are also used in chemical plants and power plants with multiple processes. Check valves are also used when there are multiple gases in a pipeline.

6. Needle Valves

Needle valves are named for the needle-like shape of their discs. Needle valves have a long, conical needle-like point for relatively fine adjustment of fluid flow. They are sometimes used as components of other valves because the needle allows the size of the fluid flow opening to change gradually. The mechanism of action is similar to that of a globe valve. Needle valves provide greater precision and control in smaller piping systems. Still part of the quarter-turn series, needle valves function better at low flow rates.

 

Advantages

Efficient control of fluid media, suitable for finely regulated flows.

Ideal for vacuum service or any system requiring precision.

Minimal mechanical force is required to seal the valve.

 

Applications

Needle valves are used in instruments that require more complete control of fluid fluctuations and more precise fluid flow. Needle valves are more commonly used in calibration applications. They are also associated with distribution points in piping systems where needle valves are used as regulators of the media.

 

7. Pinch Valves

Pinch valves, also known as pinch valves, are another type of valve used for stop/start and throttling. A pinch valve consists of a sleeve molded from rubber or other synthetic material and a pinch mechanism. The pinch mechanism (stem or gate) is lowered onto the valve body to shut off the flow through the system. Pinch valves are part of the linear motion valve family. Linear motion allows the medium to flow unobstructed. The clamping mechanism of the clamping tube inside the valve serves to control the flow of fluid.

 

Advantages

Simple design with no internal moving parts.

Ideal for slurries and thicker, even corrosive media.

Helps prevent media contamination.

Low maintenance costs.

 

Applications

Pinch valves are primarily used for unrestricted fluid flow. They are best suited for slurry applications. Pinch valves are ideal for applications that require complete isolation from valve components and environmental contaminants.

Other applications that use pinch valves include wastewater treatment, chemical treatment, cement handling, etc.

 

8. Plug Valves

A rotary motion valve is used to stop and start fluid flow. Plug valves are part of the angle travel valve family. The disc acts as a gas-tight shutoff device and is located on a plug or cylinder. Due to its conical end and appropriately named plug valve. Its closing and opening mechanism is similar to that of a ball valve. The disc is a solid conical or cylindrical plug with a bored passage at right angles to the longitudinal axis of the plug. When open, the plug is aligned with the inlet and outlet of the valve body. The plug is either round or cylindrical with a taper.

 

Advantages

Simple mechanism.

Easy in-line maintenance.

Low-pressure drop.

Reliable, tight-sealing capability.

Quick opening or closing with just a quarter turn.

 

Applications

Plug valves are effective in tight closing and opening valves. There are many applications that use plug valves. These include natural gas pipelines, slurries, applications containing large amounts of debris, and high temperature and pressure applications.

These valves are well suited for wastewater systems. Plug valves are also well suited for highly abrasive and corrosive media because there is no contact between the media and the internal valve components.

 

9. Pressure Relief Valves

A pressure relief valve is a valve that relieves or limits pressure in a pipeline to maintain pressure balance and avoid buildup. It is sometimes mistakenly referred to as a pressure safety valve.

 

Its primary purpose is to protect equipment in the event of an overpressure event or to increase pressure in the event of a pressure drop. There is a predetermined pressure level and if the latter exceeds the preset level, the valve will release additional pressure.

 

Advantages

Can be used in all types of gas and liquid applications.

Can also be used for high pressure and high-temperature applications.

Cost-effective.

 

Applications

Pressure-reducing valves are effective when backpressure is not a major consideration. Pressure-reducing valves can be seen in boiler applications and pressure vessels.

 

In summary - choosing the right valve for your piping system

These are the 9 types of valves used in industry today. Some act as tight protection against leaks, while others make great throttling valves. The most important question to ask yourself when looking for a valve is what do you need the valve to do? Valves are an important use in any piping system. Whatever the requirements of your system, there is always a valve that will serve that purpose. By understanding each valve, it becomes easier to learn how to apply them to your industry.
