Product Information DIRECTIONAL VALVEPilot-Operated, Hydraulic Check Valve Type: PC10 Operating pressure: 250 bar (3600 psi) Proof pressure: 350 bar (5000 psi) Flow: 30.2 L/min Description A screw-in, cartridge type, pilot-operated hydraulic check valve, which can be applied for unidirectional blocking or load holding circuits. Operation PC10 allows flow from @ to © , while blocking flow from the opposite direction. When the sufficient pressure is applied at © , the fluid can flow from © to @ . The pilot ratio for this type of valve is 4:1, which means that the valve cannot be opened until at least 1/4 of the load pressure of © is applied at © . Under the static or noload conditions, the valve is spring-biased to assure holding. A sealed pilot piston optional is available. Provide customized based-spring. Please contact customer service.
