Characteristics
The WCB gate valve is a universal gate valve made of ASTM A216 WCB carbon steel casting as the core material of the valve body, following standards such as API 600/ASME B16.34. Its core characteristics include material mechanical balance, reliable sealing, wide adaptability to working conditions, and excellent economy. It is suitable for industrial cut-off scenarios ranging from medium low pressure to medium high pressure, and non strong corrosion.

Advantages
1. Small torque of gate valve
The flow channel is straight, with low resistance and moderate opening and closing torque, suitable for cutting off large diameters and high flow rates.
2. Wide range of applications for the slide valve
Suitable for non corrosive media such as water, steam, oil, natural gas, etc., widely used in petroleum, chemical, power, municipal, etc.
3. High reliability and performance
Mature structure, low maintenance frequency, fire/anti-static design enhances system safety.

Packing
Standard export wooden case packaging

Application Scenarios
The WCB sluice valve widely used for on corrosive/weakly corrosive media such as water, steam, oil, natural gas, neutral gas, etc.
