Notes For Use Of Cast Iron Butterfly Valves

We are a leading Cast Iron Butterfly Valve suppliers. Today we are going to talk about the matters needing attention when using cast iron butterfly valves. Check the specification, pressure, temperature and corrosion resistance of cast iron butterfly valve before installation. All parts should be inspected for damage or looseness.

(1) this butterfly valve can be installed on pipelines at any Angle, and it is advisable to close the installation; When welding the pipe flange, the valve sealing port should be blocked with a plate to prevent the particles and debris from contusion sealing surface.

(2) remove the valve after welding, clean the sealing cover of the valve and the inner cavity of the pipe, and then install the fixed valve.

(3) pay attention to the pressure direction of the valve in the closed state during installation.

(4) before installation, the sealing surface (both end sealing surface, butterfly plate sealing surface and seat sealing surface) shall be thoroughly cleaned to remove dust and dirt.

In fact, in addition to supplying butterfly valves, we also provide Swing and Lift Check Valve. Welcome to contact us!

Some Knowledge Of Flanged Center Line Butterfly Valve

What do you know about Flanged Center Line Butterfly Valve?

According to different structural forms, it can be divided into middle line butterfly valve, single eccentricity butterfly valve, double eccentricity butterfly valve and three eccentricity butterfly valve. The middle line butterfly valve is usually sealed with soft seal. Eccentric butterfly valve with hard seal. Three-eccentric butterfly valve is the best performance valve at present, both soft sealing butterfly valve excellent sealing performance, and hard sealing butterfly valve high temperature, high pressure corrosion resistance characteristics.

According to the different connection forms, it can be divided into dual butterfly valve, flanged butterfly valve, welded butterfly valve, screw butterfly valve, clamp butterfly valve and so on. So do you know how it came about?

We are a professional Flanged Center Line Butterfly Valve Supplier, we provide flange center line butterfly valve, and also provide DIN Angle Globe Valve, welcome to contact us!

How The Butterfly Valve Works?

Butterfly valve such as Flanged Center Line Butterfly Valve is a valve that USES a circular disc as an opening and closing piece and rotates with the stem to open, close, and regulate the flow passage. Butterfly valves are mounted on the diameter direction of the pipe. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 ° ~ 90 °, rotate to 90 °, the valve is fully open. The flow rate of the medium can be controlled by changing the deflection Angle of the plate.

Butterfly valves are often used for conveying corrosive and non-corrosive fluid media in engineering systems such as furnaces, gas, natural gas, liquefied petroleum gas, cold and hot air, chemical smelting, etc., and for regulating and blocking the flow of media.

As a matter of fact, In addition to this product, we also provide Gost Check Valve China. We are aslo Gost Globe Valve Supplier. So We can meet all your needs. You can contact us at any time if you want more details.

Basic Valve Purchase Criteria

In the market, you may see a lot of China Industrial Valves Brand, but you may not know some of the rules when buying industrial valves.

What function would you like to perform if you want to use a valve? General valves have functions of starting and stopping fluid, regulating flow, preventing backflow, regulating pressure and reducing pressure. Which one do you want?

2. What is the media through? What is the pressure/temperature requirement? In addition to the manufacturer's brand name and valve size, it is a basic service rating that appears on most valve bodies.

3. Valve structure and internal structure. Brass valves, bronze valves, cast iron valves, carbon steel and stainless steel valves, alloy valves and other materials also have different applications.

When choosing the right valve, it is also important to choose the right operator. The choice of manual or electric actuators (pneumatic/electric/hydraulic) depends on several factors.

Want To Learn About Cast Iron Butterfly Valve? Come on, Tt's All Summed Up Here

Cast Iron Butterfly Valve is a kind of Butterfly Valve, it is also called flip plate valve, it is a simple structure of the control valve, but also can be used for low pressure pipeline medium switch control. Industrial butterfly valves are characterized by high temperature resistance, high applicable pressure range, large nominal valve size, carbon steel valve body, and metal ring instead of rubber ring for the disc seal ring. Large - temperature butterfly valves are welded steel plate manufacturing, mainly used for high - temperature medium smoke duct and gas pipeline.

The other thing I want to tell you is the Electric Drive Type Butterfly Valve that many people have mentioned. This product is mainly used in various industrial automation production pipeline flow, pressure, temperature control. For example: electricity, metallurgy, petrochemical, environmental protection, energy management, fire control system, etc.
