Rexroth 3DR10P Series Pilot Operated 3-Way Pressure Reducing Valves

Product Overview: The Rexroth 3DR10P Series is a high-performance, pilot-operated 3-way pressure reducing valve designed for precise pressure control in secondary hydraulic circuits. Its unique 3-way configuration not only reduces a higher primary pressure to a constant secondary setpoint but also features an integrated relief function. If the pressure in the secondary circuit rises above the setpoint due to external forces, the valve acts as a relief valve, venting oil to the tank. This makes the NG10 (Size 10) version an essential component for machine tools, metallurgical equipment, and industrial power units.

Featured models on this page include the high-pressure R900916661 (3DR10P5-6X/315Y/00M) and the versatile 100Y and 200Y range specifications.

Key Technical Advantages:

• Integrated 3-Way Control: Combines pressure reduction and overpressure relief in one unit, ensuring actuator stability and protecting secondary systems from surges.

• Pilot-Operated Precision: Provides superior pressure regulation accuracy with minimal hysteresis, even under fluctuating flow conditions, compared to direct-operated valves.

• 6X Design Series: Built on the latest Rexroth 6X platform for enhanced hydrodynamic efficiency and extended service life.

• Flexible Adjustments: Multiple spring ratings (100, 200, 315 Bar) available, with manual knob or hex screw adjustment options for precision tuning.
