Product Overview
The Rexroth DBETX-10/250G24-8NZ4M (Material Number: 0811402019) is a pilot-operated proportional pressure relief valve from the DBETX series, engineered for precise, infinitely variable electro-proportional pressure control in industrial hydraulic systems. Unlike fixed-setting relief valves, this unit modulates system pressure in direct proportion to the electrical command signal applied to its integrated proportional solenoid, enabling smooth pressure ramping, load-independent pressure regulation, and programmable pressure profiles. The valve combines a pilot stage with a main spool stage, where the solenoid force acts against a pilot poppet to establish a command pressure that is amplified to the main stage, delivering high flow capacity with excellent resolution and repeatability. With a nominal pressure rating of 250 bar and a 24 VDC solenoid, the DBETX-10/250G24-8NZ4M is a direct-fit, high-performance solution for demanding pressure-control circuits in injection molding, metallurgy, and heavy machinery applications.

Engineering Features & Advantages
- Precision Proportional Control: The proportional solenoid and pilot poppet design deliver a pressure output that is continuously variable and directly proportional to the electrical command signal, enabling precise pressure ramping and programmable pressure profiles without mechanical adjustment.
- High-Resolution Pressure Regulation: Pilot-operated two-stage architecture provides fine pressure resolution and stable regulation across the full 250 bar range, with minimal hysteresis and excellent repeatability for closed-loop pressure control.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust spool and poppet construction that resists contamination-induced sticking and ensures long service life.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
