Product Overview
The Rexroth DREE10-61/200YG24K31F1M (Material Number R901278156) is a direct-operated, pilot-assisted proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. Part of the Rexroth DREE series, this valve reduces a primary system pressure to a lower, electrically commanded secondary pressure at port A, maintaining it constant regardless of flow demand or load fluctuations. Actuation is achieved via a high-response proportional solenoid (24 V DC) that positions the control spool proportionally to the input current, enabling stepless pressure regulation with minimal hysteresis and excellent repeatability. The integrated pressure relief function protects the secondary circuit against inadmissible pressure spikes. With a nominal size of NG10 (Size 10) and a maximum secondary pressure setting of 200 bar, this valve is engineered for demanding applications requiring accurate force, torque, or pressure modulation.
