What is Piston Check Valve ?  Piston Check valve Parts

May 15, 2018· Piston Check Valve A piston check valve is essentially a lift check valve. It has a dash pot consisting of a piston and cylinder that provides a cushioning effect during operation. Because of the similarity in design to lift check valves, the flow characteristics through a piston check valve are essentially the same as through a lift check valve.

Selection of Valves: Valve Selection Procedure  What Is

Valve Selection Based on Valve Function. There are two basic principles on which valves are constructed. 1 The first principle is developed in three ways: Moving the stopper by direct thrust on to the orifice seating. This obturating movement is the basis of globe type valves. Rotating the stopper. This is the basis for plug or ball type valves.
