Piston Check Valves are unidirectional flow valves and are used with different process fluids.
Piston Check valves work automatically: they do not require external control or an operator. For this reason, these valves do not have a handwheel.
Piston Check valves can be used when an almost total passage of fluid is required, although the flow rate should not be excessively high.
The main component of Piston Check valves is the piston-shaped disc. Closing automatically, the disc allows the interruption of the flow and the closure of the valve. If the pressure is not enough, the valve remains closed; when the pressure is enough, the valve opens and the fluid is free to pass.
Piston Check Valves can also have an Y shape
