Description & Features
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.
