Rexroth S20A, G1Inch threaded connection non return valve allows hydraulic oil flow in one direction but not the reverse direction of the flow. The valve works with hydraulic pilot operated check valve. Hydraulic system hydraulic oil through hydraulic pump increases the pressure and flows into the P port of entry, to overcome the spring force and the friction of the one - way valve open, the hydraulic oil flows to T from P.
When the P port hydraulic oil in the spring force is same with T port oil force, the valve turns off, so from T to P should no leakage.

Rexroth S20A, G1Inch Threaded Connection Non Return Valve
The Rexroth S20A, G1Inch threaded connection non return valve does not allow the occasion of the reverse flow of hydraulic oil , set up a one-way valve between the oil tank and hydraulic actuators, especially when the hydraulic oil is added to the tank of the hydraulic system. If a pump stopped working, the valve prevents the hydraulic oil in the hydraulic tank reflux to the hydraulic system. The check valve is also often combined with the throttle valve, sequence valve into a one-way throttle unidirectional sequence valve.
