Product Overview
The Rexroth DBEM20-71/315YG24K4M (Material Number: R901353042) 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 simple on/off valves, the DBEM20-71/315YG24K4M allows for stepless adjustment of the system pressure proportional to the electrical input signal, enabling sophisticated load sensing, force control, and pressure profiling. It serves as a critical safety and control component, capable of limiting system pressure while also acting as a dynamic actuator for pressure-reducing or sequencing functions.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool position and resulting pressure are infinitely variable, allowing for exact pressure regulation that is directly proportional to the electrical command signal. This eliminates pressure shocks and enables smooth ramp-up and ramp-down profiles.
- Integrated Electronics (OBE): The “K4M” designation indicates an integrated control amplifier mounted on the solenoid. This simplifies wiring, reduces installation space, and improves signal-to-noise immunity, ensuring stable performance in electrically noisy industrial environments.
- High-Pressure Capability: With a rated pressure of 315 bar, this valve is engineered for high-pressure circuits, providing reliable overload protection and pressure limiting without compromising system dynamics.
- Robust Pilot-Operated Design: The pilot stage ensures fast response times and high flow capacity with minimal pressure drop, while the main stage handles the high flow requirements of large actuators.
- Direct Fit Replacement: Manufactured to exact Rexroth OEM specifications, ensuring dimensional and functional interchangeability with existing DBEM series valves.
Typical Industrial Applications
This proportional pressure relief valve is ideally suited for advanced hydraulic systems requiring dynamic pressure control. Common applications include plastic injection molding machines (for precise clamping and injection pressure profiling), metallurgical presses (for force-controlled forming), CNC machine tools (for tool clamping and counterbalance circuits), and test stands where programmable pressure cycles are essential. It is also used in marine and offshore hydraulic systems for safe, remote pressure adjustment.
