What is its gate seal pressure?

Reply #2 2017-03-03

If a gate valve is of the wedge-type variety, it operates on a torque-sealing principle; sealing is achieved through the tight fit that occurs when the wedge-shaped gate plate and its two sealing surfaces come into contact with the two sealing surfaces on the valve body. The pressure on the gate plate is related to this fitting force. If you want to know what pressure level a valve can withstand, you should refer to ASME B16.34, which provides a temperature-pressure curve. For example, a CL150 WCB valve can withstand 1.92 MPa at 50°C and 1.02 MPa at 300°C.

The sealing pressure limit is related to the operating temperature, medium, and vibration; ASME provides relevant regulations for reference. Hope this helps you
