Product Overview
The Rexroth Z3DREE 10 VP2-10/315XLG24K31A1M (Material Number: R901483247) is a high-performance, direct-operated proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As part of the Rexroth DREE series, this valve functions as a pilot-operated, 3-way pressure reducing valve that maintains a constant reduced outlet pressure (port A) regardless of fluctuations in the primary supply pressure (port P) or changes in flow demand. The integrated proportional solenoid converts an electrical current signal into a proportional mechanical force, enabling stepless adjustment of the set pressure. This valve is specifically engineered for applications requiring accurate pressure regulation, smooth response, and high repeatability, making it a critical component in modern electro-hydraulic control loops.

Engineering Features & Advantages
- Precision Proportional Control: The valve provides infinitely variable pressure adjustment via a proportional solenoid, allowing for exact matching of system pressure to process requirements. The integrated electronics (OBE) ensure high repeatability and minimal hysteresis, critical for closed-loop pressure control.
- 3-Way Pressure Reducing Function: Unlike 2-way reducers, the 3-way design (P to A, A to T) actively relieves excess pressure from the secondary circuit, preventing pressure spikes and ensuring stable reduced pressure even under varying flow conditions.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
