Forged steel Y type piston check valve

Forged steel Y type piston check valve

A piston check valve, is essentially a lift check valve. It has a dashpot 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. Installation is the same as for a lift check in that the flow must enter from under the seat. Construction of the seat and disk of a piston check valve is the same as for lift check valves. Piston check valves are used primarily in conjunction with globe and angle valves in piping systems experiencing very frequent changes in flow direction. Valves of this type are used on water, steam, and air systems.

Forged steel Y type piston check valve is a kind of piston check valve made from forged steel and it is Y type. Forged steel makes the check valve substantial. And this check valve is popular with many occasions.
