Understanding API 603 StandardsWhat is API 603?API 603 is a standard developed by the American Petroleum Institute that specifies the requirements for steel gate valves, including wedge gate valves, used in pipeline service. Compliance with API 603 ensures that these valves meet stringent quality an

I. Sealing Performance(I) Wedge Gate ValveThe sealing performance of the wedge gate valve mainly depends on the tight combination of the wedge-shaped gate and the valve seat. Its sealing surface forms a certain angle with the vertical centerline (usually 2°52', 3°30', 5°, 8°, 10°, etc.). This design

I. Advantages of Traditional Sealing Design(I) Rigid Gate and Flexible GateThe gate of a wedge gate valve can be designed as a rigid gate or a flexible gate. The rigid gate has strong integrity and is suitable for high-pressure working conditions. The flexible gate, through the elastic groove in the
