According to The Direction of Access, What Kinds of Globe Valves?

According to the channel direction, globe valves such as Gost Globe Valve are divided into many types:

1. Straight through type stop valve

Medium on the import and export channels in the same direction, in 180 °, the flow state of less damage, loss of pressure across the valve is relatively small.

2. Straight flow stop valve

The stem and channel are at an Angle, the seat sealing face and the inlet and outlet channels are at an Angle, and the flow direction is almost unchanged. Suitable for piping with coking and solid particles.

3. Angle globe valve

Medium on the import and export channel is not in the same direction, in 90 ° Angle, will produce a certain pressure drop, the biggest advantage is that can be installed in the corner of pipeline system, the elbow, saving and convenient operation.

Same reason, according to certain standard differentiate, Check valve such as Gost Check Valve also can have a lot of kinds.

Seven Structural Features Of Water-sealed Globe Valve

Do you know some structural features of Water-sealed Globe Valve?

1. Select materials carefully, conform to relevant standards at home and abroad, and the materials are of high overall quality.

2. The sealing pair is advanced and reasonable, which improves the sealing performance and long service life.

3. The product is designed and manufactured according to national standard GB/T12235 with novel structure and beautiful shape. The connecting end has flanges and welding, which can be connected according to different requirements of users.

4. The packing box is designed into water seal structure, which is connected with water filler of 0.6 ~ 1.6 pa. With low friction and good sealing, it can isolate the air of the system and ensure good air tightness.

5. The valve stem is provided with good corrosion resistance, abrasion resistance and abrasion resistance through the process of tempering and surface nitrification.

6. Compact structure, flexible operation and convenient maintenance.

7. The inverted seal is made of stainless steel threaded connection seal or body surfacing austenite stainless steel, and the seal is reliable. Packing replacement can be carried out without stopping the machine, which is convenient and fast without affecting the system operation.

We supply a wide range of Water-sealed Globe Valve. If you have any requirement, please feel free to contact us. Besides, we're still a Gost Gate Valve Suppliers Meeting your needs.

What Is A 10K Elastic Deat Gate Valve

The 10K Resilient Seat Gate Valve has two sealing faces. The two sealing faces of the most common mode gate valves form a wedge shape, and the wedge angle varies with valve parameters. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its process-ability and compensate for the deviation of the sealing surface angle during the machining process. The board is called a resilient shutter.

The elastic seat sealing gate valve is also called the lifting rod gate valve. Usually there is a trapezoidal thread on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end of the valve and the guide groove on the valve body, that is, the operating torque is changed to the operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a mark, that is, the position where the valve is opened, as its fully open position. In order to consider the temperature change, there is a lock-up phenomenon, usually at the position of the opening to the apex, and then back to 1/2-1 lap as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the shutter.

What's The Difference Between Cast Iron Valve And Cast Steel Valve

As an iron valve supplier we Wholesale Cast Iron Valve such as China Cast Iron Gate Valve. Today we are going to popularize cast iron valve and cast steel valve what is the difference.

The main difference between cast iron and steel valves is carbon content, which directly affects steel strength and plasticity. Carbon steel is also known as carbon steel. Carbon steels generally contain a small amount of silicon, manganese, sulfur, and phosphorus. Carbon structural steels are divided into structural steels for architecture and structural steels for machine manufacturing. Carbon steels can be divided into low carbon steels (WC less than 0.25%), medium carbon steels (WC0.25% -- 0.6%) and high carbon steels (WC>. According to phosphorus and sulfur content, carbon steels can be divided into ordinary carbon steels (with higher phosphorus and sulfur), high-quality carbon steels (with lower phosphorus and sulfur) and high-quality steel (with lower sulfur and sulfur).

In addition, we are also a Cast Iron Gate Valve Manufacturer. If you have any professional knowledge, please feel free to contact us!

Why Should The Stop Valve Be Low In And High?

Globe valves such as DIN Angle Globe Valve are designed to be low in and high in order to reduce flow resistance and save effort when opening the valve. At the same time, when the valve is closed, the gasket between the valve shell and cover and the packing around the valve stem will not be stressed, and the effect of medium pressure and temperature for a long time will prolong the service life and reduce the probability of leakage. In addition, the valve can be closed to replace or add filler for easy maintenance.
