Wafer Flanged Valves

About Wafer Flanged Valves

Wafer flanged refers to a hybrid valve design that combines features of both wafer-style and flanged connections. The valve body is shaped to fit between two flanges like a wafer valve but also includes alignment holes or tabs that help position it precisely within the flanged connection. Unlike full flanged valves, wafer flanged valves are not bolted directly through their own flanges.

How Does It Work?

A wafer flanged valve is installed by placing it between two standard pipe flanges. Flange bolts pass around the valve, using the pipe flanges to clamp the valve in place. Some wafer flanged valves include alignment holes or lugs to aid in centring the valve and aligning it with bolt holes. Gaskets are placed on both sides of the valve to ensure a tight seal. The valve remains securely in place due to the flange pressure, not direct bolting through the valve body.

Why Is It Used?

• Slim and compact design for space-limited installations
• Lighter and more economical than full flanged valves
• Easy to install between existing flanges
• Allows for precise alignment, helping to reduce installation errors
• Suitable for general service applications with moderate pressures

Common Uses:

• Water distribution systems
• Building services and HVAC
• Industrial pipelines with standard flange connections
• Applications needing space efficiency and easy installation
• Ideal for butterfly and check valves
