S10P05-1X/

The S10P05-1X/ valve belongs to the Type S Check Valves series from Bosch Rexroth and is intended to secure hydraulic circuits by permitting flow toward actuators while preventing reverse flow during load holding or safety shutdowns. The valve type is a check configuration that blocks return flow once system pressure falls below its opening threshold. A cracking pressure of 0.5 bar allows the poppet to open with minimal upstream pressure, protecting pumps from excessive back-pressure. Installation is by a threaded screw-in body, and the connection thread is 3/4-16 UNF, allowing direct integration into standardized manifolds or custom blocks. The nominal size 10 passage provides adequate flow capacity for medium line diameters, while a maximum operating pressure of 450 bar lets the component withstand high-pressure mobile or industrial drives. The check element is leak-free in one direction, so downstream loads remain fixed without the need for external mechanical locks.

The S10P05-1X/ accepts several mineral-oil and synthetic media to fit diverse plant requirements. Approved hydraulic fluids include HL, HLP, HLPD, HVLP, and HVLPD, and flame-resistant HFC or HFDU fluids can also be used when fire safety standards apply. Bosch Rexroth specifies a cleanliness class of 20/18/15 per ISO 4406, so filtration must maintain particle counts below this level to avoid premature wear of the sealing surfaces. Mean time to dangerous failure is rated at 150 years, indicating high statistical reliability for long-term installations that cycle infrequently but demand constant readiness. The compact body weighs 0.3 kg, which simplifies handling during service and reduces manifold mass in weight-sensitive equipment. These characteristics complete the functional profile and show how the component maintains consistent performance across a broad range of operating conditions.
