Product Overview
The Rexroth DBEM10-71/100YG24K4M (Material Number: R901335402) is a high-performance, pilot-operated proportional pressure relief valve designed for precise, continuous pressure control in demanding industrial hydraulic systems. Part of the renowned Rexroth DBEM series, this valve combines the robust construction of a classic pressure relief valve with the infinitely variable control of a proportional solenoid. Unlike standard on/off relief valves, the DBEM10-71/100YG24K4M allows for stepless adjustment of the system pressure proportional to the electrical input signal, enabling smooth ramping, load holding, and precise force control. It serves as a critical safety and control component, protecting hydraulic circuits from overpressure while facilitating dynamic pressure regulation in complex machinery.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool position and resulting system pressure are infinitely variable and directly proportional to the solenoid current, allowing for precise force and torque control in automated processes.
- Integrated Safety Function: Functions as a traditional pressure relief valve, providing fail-safe protection against system overpressure even in the event of electrical failure, ensuring machine and operator safety.
- Low Hysteresis & High Repeatability: Engineered for minimal signal hysteresis and excellent repeatability, ensuring consistent performance across millions of cycles in closed-loop control systems.
- Robust Pilot-Operated Design: The pilot stage amplifies the proportional control signal, allowing for stable pressure regulation even at high flow rates and varying system loads.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring seamless integration into existing manifolds and systems.
Typical Industrial Applications
This proportional pressure relief valve is ideally suited for a wide range of heavy industrial applications requiring precise pressure modulation. Common uses include plastic injection molding machines for precise clamping and injection pressure control, metallurgical presses for controlled forging and stamping forces, CNC machine tools for tool clamping and counterbalance circuits, and general hydraulic test stands where variable pressure profiles are essential. Its robust design also makes it suitable for construction and marine hydraulic systems that demand reliable, dynamic pressure regulation.
