Product Overview
The Rexroth DBETBEX-10/180G24K31A1M is a pilot-operated proportional pressure relief valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. Part of the Rexroth DBETBEX series, this valve combines a pilot stage with a proportional solenoid actuator to deliver continuously adjustable system pressure setting proportional to the electrical command signal. Unlike fixed-setting relief valves, the DBETBEX-10/180G24K31A1M enables dynamic pressure regulation, ramping, and load-adaptive control directly from a PLC or amplifier card. With a nominal size of NG10 (size 10) and a pressure rating of up to 180 bar, it is engineered for demanding applications requiring accurate pressure limiting, pressure sequencing, and smooth pressure transitions. The integrated 24V DC proportional solenoid (G24) with spring return ensures fail-safe behavior, while the K31A1M designation indicates the specific solenoid voltage, connector type, and adjustment configuration. This valve is a direct-fit replacement for OEM Rexroth proportional pressure relief valves in the DBETBEX family.
