Product Overview
The Rexroth DBEM20-71/200YG24K4M (Material Number: R901353036) is a high-performance proportional pressure relief valve from the renowned Bosch Rexroth DBEM series. This pilot-operated valve is designed to provide infinitely variable pressure control in hydraulic systems, converting an electrical input signal into a proportional hydraulic pressure output. Unlike simple on/off relief valves, the DBEM20-71/200YG24K4M allows for precise, dynamic pressure regulation and remote control capabilities, making it an essential component for advanced industrial automation, load sensing, and pressure-limiting circuits. It features an integrated proportional solenoid (identified by the “YG24” code, indicating a 24V DC supply) and is engineered for high-resolution response and excellent repeatability.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool position and resulting system pressure are directly proportional to the electrical command signal, enabling smooth, stepless pressure adjustment and precise ramp functions.
- Integrated Electronics (K4M): Features an integrated control amplifier (identified by the “K4M” suffix) which ensures optimized solenoid current control, reducing hysteresis and improving dynamic response for closed-loop pressure control systems.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction that withstands high pressure and demanding duty cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring seamless integration into existing Rexroth hydraulic power units and manifolds.
Typical Industrial Applications
This proportional pressure relief valve is widely utilized in heavy industrial scenarios requiring precise force or torque control, including plastic injection molding machines (for clamping and injection pressure control), metallurgical presses, hydraulic test stands, and CNC machine tools. It is also commonly found in marine and offshore hydraulic systems where remote pressure adjustment and safety relief functions are critical.
