What role does the hydraulic system check valve have?

Check valve is used to prevent the reverse flow of oil flow in the hydraulic system, used to prevent the reverse flow of compressed air in the pneumatic system, is the fluid can only flow along the inlet, the outlet medium can not return.
 
One-way valve in the hydraulic system used in several ways:
 
(1) if the one-way valve is installed at the pump port, it can prevent the sudden increase of system pressure from damaging the oil pump.
 
(2) if the one-way valve and throttle valve or pressure reducing valve parallel structure actuator to slow reverse fast; Or reverse the free flow path to the deceleration.
 
(3) if the one-way valve and pressure valve in series, gradually increase the adjustment pressure, prevent pressure reaction.
 
(4) for the liquid control one-way valve, use the control oil circuit to open the one-way valve so that the oil cannot flow back in reverse.
