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.

● Replaceable seat.

● A variety of body and interior materials.

● The design of piston and valve seat, acting on the piston back pressure, sealing performance is excellent.

● These valves are unidirectional valves and restrict flow from opposite direction.
