Wedge Disc Gate Valve

Wedge Disc Gate Valve

The Wedge Disc Gate Valve uses a wedge-shaped gate to vertically lift and lower, enabling the opening, closing, and isolation of pipeline media. It is suitable for water, oil, gas, steam, and general industrial media, primarily used for on/off isolation, and is not suitable for long-term throttling.

Core Advantages

 

Reliable Wedge Sealing: The mechanical wedge structure forms a stable seal, facilitating reliable pipeline isolation and suitable for industrial on/off operations.

 

Low Flow Resistance: The full-bore flow path reduces internal resistance and lowers pressure drop in the fully open state, making it suitable for high-flow-rate systems.

 

Flexible Material Selection: A variety of valve body and internal component materials are available to match the medium, temperature, pressure, and corrosive environment.

 

Multiple Actuation Options: Supports handwheel, gear, pneumatic, and electric actuation, adaptable to manual operation and various automated control systems.

 

Wear-Resistant Sealing: The sealing surface can be configured with wear-resistant materials to improve wear resistance and erosion resistance, suitable for high-temperature and special media conditions.
