What Is a Wedge Gate Valve?
A wedge gate valve is a linear motion isolation valve widely used in industrial pipeline systems. As a typical design provided by a wedge gate valve manufacturer, the wedge-shaped disc moves between seats to achieve reliable shut-off. This structure ensures tight sealing and low flow resistance, making wedge gate valves ideal for full open or full close service.

Key Features of Wedge Gate Valve
Reliable Tight Shut-Off
The wedge disc design provides close sealing contact with the valve seats for dependable isolation performance.
Low Flow Resistance
When fully open, the valve offers a straight-through flow path with minimal pressure drop.
Durable Service Life
Precision machining and robust construction help ensure long-term operation in demanding industrial systems.
Wide Industrial Use
Suitable for oil & gas, petrochemical, power generation, water treatment, and general process applications.

FAQ
What is the difference between wedge gate valve and parallel slide gate valve?
A wedge gate valve uses a wedge-shaped disc to achieve sealing through wedging action, while a parallel slide gate valve uses parallel sealing elements. Wedge gate valves are more commonly used for general industrial shut-off service.
Can wedge gate valves be used for throttling?
No. Wedge gate valves are designed mainly for full open or full close service. Using them for throttling may damage the sealing surfaces and reduce valve life.
What materials are available for wedge gate valves?
Common materials include WCB, LCB, WC6, WC9, CF8, CF8M, duplex stainless steel, and other alloy steels according to service conditions.
Do you support customized wedge gate valves?
Yes. We can provide custom size, pressure class, material, trim, actuator, marking, and inspection requirements based on your project specifications.
What is the difference between API 600 and API 602 gate valves?
API 600 generally covers larger size cast steel gate valves, while API 602 is typically used for forged steel small-bore valves applied in high-pressure service.
What industries use industrial gate valves?
Industrial gate valves are widely used in oil & gas, petrochemical, refinery, power generation, water treatment, and general pipeline systems requiring dependable shut-off service.
