S15P15-1X/V

The S15P15-1X/V check valve belongs to the Type S Check Valves series from Bosch Rexroth and is installed in hydraulic circuits to permit flow in only one direction. With a nominal size of NG 15, it matches pipework that carries medium-range flow rates in industrial machinery. A body diameter of 34 mm provides a compact envelope while still allowing the required passage area for oil. Overall length is 72 mm, so the component fits into short manifolds, and the 13 mm thread engagement depth supports secure seating in cartridge cavities. A hexagon width across flats of 30 mm gives technicians a clear wrench surface for precise torque during assembly. Its weight of 0.5 kg keeps handling effort low when multiple valves are inserted on a manifold block.

The valve withstands a maximum operating pressure of 450 bar, enabling use on high-pressure supply lines without loss of integrity. A cracking pressure calibrated to 1.5 bar ensures the poppet lifts only when the upstream side reaches that threshold, preventing unintended reverse flow at lower pressures. Cleanliness class ISO 4406 (c) 20/18/15 defines the allowable particle count in the fluid, reducing the risk of seat wear and leakage. An MTTFd of 150 years indicates exceptionally long mean time to dangerous failure, supporting compliance with safety-related control functions in automated hydraulic equipment.
