Frequently Ask Questions

What Is a Wafer Type Disc Check Valve?

A Wafer Type Disc Check Valve is an automatic non-return valve that allows fluid to flow in one direction and prevents reverse flow. The valve uses a spring-loaded disc that opens under forward-flow pressure and closes when flow stops.

Why Is It Called a Wafer Check Valve?

It has a compact, thin body designed to be installed between two pipe flanges, rather than having integral flanges of its own.

Can It Prevent Backflow?

Yes. Backflow prevention is its primary function.

How Does It Work?

During forward flow, the pressure of the fluid pushes the disc away from the seat. When the flow decreases or reverses, the spring pushes the disc back onto the seat, preventing backflow.

Does It Require an Actuator?

No. The valve is self-acting and operates through fluid pressure and its internal spring.

Who Is a Wafer Type Disc Check Valve Manufacturer in India?
