Detail Information
Wafer Piston Check Valve
Piston check valves are automatic valves that open with forward flow and close against reverse flow. The main function of a check valve is to protect mechanical equipment in a piping system by preventing fluid reversal
Wafer Piston Check Valve-Features
Short length, small volume and light weight
Hard material welded sealing surface, which is wearing resistant, erosion proof, abrasion proof and long-lived;
With a small starting pressure, the valve discs can be fully opened under a very small pressure difference
Fast discs closing and small water hammer pressure;
Convenient installation and applicability on both level and vertical pipes
Different materials for the parts, sizes and forms of the valves surfaces are available for free combination according to the working facts and the customer’s requirements.
Piston plate Check Valve is economical on installation and maintenance because installation is required less and light weight.
Piston plate Check Valve is possible to prevent water hammering due to closing valve disk by operating the spring in valve before back flow. Also Due-Check valve prevents large piping the for big gap water levels.
It's possible to reduce maintenance fee due to longer durability than existing check valve, easy maintenance
