Hydraulic-Operated Check Valve
Hydraulic-operated check valve allows oil to flow in only one direction, and it can not allow the oil to flow in the opposite direction unless it uses the hydraulic control.
Hydraulic-operated check valve can be used as two way on-off valve, and also can be seen as a pressure retaining valve or a sustaining valve of the standing fluid cylinders.
