Product Overview
The Rexroth DBEE6-21/200G24K31F1M (Material Number: R901350548) is a high-performance proportional pressure relief valve from the Bosch Rexroth DBEE series, designed for precise, infinitely variable electro-proportional pressure control in demanding industrial hydraulic systems. Unlike fixed pressure relief valves, this pilot-operated proportional valve modulates system pressure in direct proportion to the electrical command signal applied to its integrated proportional solenoid, enabling continuous pressure regulation rather than simple on/off limiting. The valve features a 6-size (NG6 / CETOP 3) subplate mounting interface and is rated for a maximum pressure setting of 200 bar, with the “G24” designation indicating a 24 V DC proportional solenoid actuator. The “K31” control variant provides a specific solenoid and amplifier characteristic curve, while the “F1M” suffix denotes the electrical connection and manual override configuration. As a core component in modern electro-hydraulic control loops, the DBEE6-21 is widely deployed wherever programmable, repeatable pressure profiles are required — from force-controlled pressing operations to closed-loop torque regulation in injection molding. Its proportional spool and pressure-compensated pilot stage deliver smooth, hysteresis-minimized response across the full command range, making it an ideal interface between digital machine controllers and high-pressure hydraulic power circuits.
