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

The opening and closing components of cast steel gate valves are gate plates, whose movement direction is perpendicular to the direction of the fluid. Gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces, and the commonly used mode of gate valve is that the two sealing surfaces form a wedge shape. The wedge angle varies depending on the valve parameters, usually 50, and is 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made into a whole, called a rigid gate; 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.
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 are of the same material, both made of WCB A216 carbon steel.
2. Cast steel check valve, named Siyi, is a cast steel check valve because the WCB material body and blank are all cast.
3. Carbon steel check valve, named carbon steel check valve because the main material of WCB material is carbon steel.
