Bosch Rexroth R901109726 Hydraulic Cartridge Valve

Bosch Rexroth R901109726 is a direct-acting hydraulic cartridge valve in the VSNG-10A-20 variant (catalog 041159038520000). Part of Bosch Rexroth Oil Control, this compact cartridge valve is designed for installation in standard cartridge cavities to provide relief and pressure control in modular hydraulic manifolds. The VSNG-10A-20 designation specifies the exact seating and port configuration used in Rexroth's cartridge portfolio, enabling straightforward compatibility with Rexroth-based manifolds and cartridges. As a relief-type valve, it opens to limit system pressure and returns the excess flow to a lower-pressure circuit or reservoir when the set pressure is exceeded, protecting pumps, valves, and actuators in both industrial and mobile hydraulic systems. The cartridge form supports quick replacement within multi-valve assemblies, reducing downtime and simplifying servicing, while its ISO 7368-compatible cavity design (per Rexroth valve family standards) ensures consistent interfacing across Rexroth control solutions. Typical applications include circuit protection and pressure regulation in power units, manifolds, and retrofit modules where space is constrained and modularity matters.
