Product Overview
The Rexroth DREE20-6X/315YMG24K31A1M is a pilot-operated, 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 higher inlet pressure to a lower, electrically modulated outlet pressure proportional to the input command signal. The integrated proportional solenoid (24 V DC) enables stepless adjustment of the secondary pressure, making it ideal for applications requiring dynamic pressure regulation, load simulation, or force-controlled actuation. With a size 20 (NG20) mounting interface and a maximum adjustable pressure of 315 bar, this valve delivers high-resolution pressure control with excellent repeatability and minimal hysteresis.
