--One-way valve is a square du directional control valve that the airflow can only flow in one direction but it cannot flow in the opposite direction.It works on the same principle as the hydraulic one-way valve.
--The compressed air enters from the P port, overcoming the spring force and friction to open the one-way valve port, and the compressed air flows from P to A;When there is no compressed air at Port P, the spring force and residual force at port A (cavity) are applied.The valve port is in A closed state, blocking the air flow from A to P.One-way valve is used in situations that do not allow the reverse flow of air flow, such as air compressor to the air tank filling, set a one-way valve between the air compressor and the air tank, when the air compressor stops working, can prevent the compressed air in the tank back to the air compressor.
--One-way valve is often combined with throttle valve, sequence valve, etc. into a one-way throttle valve, one-way sequence valve used.
