Wedge Gate Valve

Wedge Gate Valve Manufacturer and Supplier

Wedge Gate Valves are usually used in industrial piping for isolating or stoping – to turn on and shut off the flow. Wedge Gate Valves have a disc in the shape of a wedge to seats against two inclined seats. You can wholesale metal seated wedge gate valves and resilient seated wedge gate valve (if drip tight shut off is required) from TianYu wedge gate valves manufacturer. They can meet the demands of different pressure and temperature conditions and are available in full port.We recommend buying your favorite toothbrush at super low prices with free shipping, and you can also pick up your order at the store on the same day.

Why Choose TIANYU Valve

The latter design consists of two independent and flexible wedge halves, that allow a relative movement to accommodate changes in the body seat angles.

The result is a valve with a high pressure sealing performance, with optimum results at low differential pressures, meeting industrial valve requirements, moved toward larger sizes and higher pressures and temperatures.

Our utmost care when machining and lapping wedge and seats, and the flexible wedge design for sizes beyond 2”, assure valve tightness on both sides regardless of the operating pressure.

Carbon steel, alloy steel, stainless steel and other valve materials may be selected depending on the fluid and pressure and temperature conditions following ASME B16.34 standard.

The standard wedge gate valves shall be outside screw and yoke, non-rotating stem, T-head stem-wedge connection and welded / threaded / integral seats. The valve can be manually operated or by means of an electric, pneumatic or hydraulic actuator.
