Piston Check Valve

These valves are much less subject to pounding with pulsating flow due to the intergral dash-pot. This makes them suitable for applications where frequent change of direction of flow occurs

There are two types of these valves. Spring loaded and unsprung. Spring loaded piston check valves can operate at any orientation while unsprung valves have to be oriented for gravity closure. These valves are not suitable for gritty liquids.
