Product Overview
The Rexroth DBETX-10/180G24-25NZ4M (Material Number: 0811402031) is a high-performance pilot-operated proportional pressure relief valve designed for precise, infinitely variable pressure control in demanding industrial hydraulic systems. Part of the Rexroth DBETX series, this valve combines a proportional solenoid actuator with a robust pilot-operated relief cartridge to deliver smooth, stepless pressure adjustment proportional to the electrical input signal. Unlike fixed-setting relief valves, the DBETX-10/180G24-25NZ4M enables dynamic pressure regulation, making it ideal for applications requiring programmable pressure profiles, soft-start/stop sequences, and closed-loop pressure control. The valve features a 24 VDC proportional solenoid, a nominal pressure rating of 180 bar, and a compact NG10 (size 10) mounting interface, ensuring seamless integration into standardized hydraulic manifolds and power units. As a genuine Rexroth component, it guarantees exceptional repeatability, low hysteresis, and long service life in continuous industrial duty.
