Product Overview
The Rexroth DRC5-52/315YS0177 (material number R900918485) is a pilot-operated pressure reducing valve from the proven DRC series, engineered to maintain a constant reduced outlet pressure regardless of fluctuations in the primary supply pressure or changes in flow demand. As a direct-operated, cartridge-style pressure control valve, it limits the pressure in a secondary circuit to a preset value, protecting downstream components such as actuators, cylinders, and precision tooling from over-pressure conditions. The valve features a robust housing, a precision-ground control spool, and an adjustable spring-loaded pilot stage that enables fine pressure setting and reliable regulation across the full industrial operating range. With a nominal pressure rating of 315 bar, this model is suited for demanding hydraulic systems requiring stable, repeatable pressure control in continuous duty cycles.
