The opening and closing component of the cast steel gate valve is the gate, and the direction of the gate's movement is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The commonly used mode of gate valve is that the two sealing surfaces form a wedge shape, and the wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, it is 2 ° 52 '. The gate plate of the wedge gate valve can be made into a whole, called a rigid gate plate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.

 

What is the difference between carbon steel gate valves and cast steel gate valves

 

Many people may think that carbon steel gate valves and cast steel gate valves are two types of valves. Below is an analysis:

 

1. Cast steel check valves and carbon steel check valves belong to the same material of check valves, both made of WCB A216 carbon steel material.

 

2. Cast steel check valve, because the valve body and blank of WCB material are all cast, it is named Siyi and is called cast steel check valve.

 

3. Carbon steel check valve, named carbon steel check valve because the main material of WCB material is carbon steel.
