The Rexroth R901424189 S10A05-10/450J3 is a high-performance, pilot-operated check valve designed as a screw-in cartridge. This valve ensures free flow from port 1 to port 2 while providing leak-free blocking in the opposite direction. The blocked flow can be released by applying sufficient pressure to the pilot port, making it ideal for applications requiring secure load holding, such as in hydraulic presses, lifting equipment, and clamping circuits. Its robust construction guarantees reliability and a long service life even under demanding conditions with pressures up to 450 bar.
