Product Overview
The Rexroth DBETX-10/80G24-8NZ4M (Material Number: 0811402018) is a high-performance proportional pressure relief valve from the Bosch Rexroth DBETX series. This pilot-operated valve functions as a continuously adjustable pressure limiting device, converting an electrical current signal into a proportional hydraulic pressure setting. Unlike conventional on-off relief valves, the DBETX design enables stepless pressure control across the full adjustment range, making it indispensable in industrial hydraulic systems requiring precise force, torque, or pressure regulation. The integrated proportional solenoid (24 V DC) actuates a pilot poppet that modulates the main spool position, delivering smooth, low-hysteresis response to command signal changes. The “80” designation indicates a nominal pressure setting of 80 bar, while the “NZ4M” suffix denotes the specific solenoid and adjustment configuration for this model. This valve is engineered for direct integration into Rexroth proportional control systems and is widely used as a critical pressure control element in injection molding, press, and test rig applications.
