Introduction of Piston Check Valve

With a piston for the disc, the seat design of piston check valve is similar to a globe valve. It has a dashpot made of a cylinder and piston that acts as protection during application. 

It is mainly used with angle and globe valves in piping systems that have periodic changes in flow directions. It is also used in high-pressure applications that have high flow velocity. Well-suited for installation in both vertical and horizontal pipelines with upward flow. It is commonly used in air, water, and steam systems. Different piston check valve dimensions can be chosen in XHVAL.
