Frequently Ask Questions
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.
It has a compact, thin body designed to be installed between two pipe flanges, rather than having integral flanges of its own.
Yes. Backflow prevention is its primary function.
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.
No. The valve is self-acting and operates through fluid pressure and its internal spring.
Alis Valves manufactures and supplies Wafer Type Disc Check Valves for industrial backflow-prevention applications. Its listed configuration includes CF8/CF8M, cast iron and cast-steel bodies, ½"–10" sizes, SS304/SS316 and other disc options, up to 10 bar operating pressure and up to 80°C operating temperature.
