Rexroth DBET Proportional Relief Valve | 0811402072 | 0811402070 | DBETBEX-1X | 315 bar

Rexroth DBE/DBET Series Proportional Pressure Relief Valves

Product Overview: The Rexroth DBET series consists of high-performance proportional relief valves (direct-operated), engineered for the stepless regulation of system pressure in hydraulic circuits. This versatile series ranges from the basic DBE to the DBETE with integrated digital electronics, the explosion-proof DBETX, and the DBETRE with position feedback. The primary advantage is the ability to adjust the opening pressure linearly based on the input current signal. For high-pressure models like 0811402070, it maintains minimal hysteresis and excellent dynamic response even at operating pressures up to 315 bar.

Featured part numbers: 0811402072 (80 bar), 0811402070 (315 bar), and the DBETBEX-1X series.

Key Technical Advantages:

• Precision Linear Pressure Regulation: Driven by proportional solenoids, these valves establish a linear relationship between system pressure and input current, ideal for complex pressure-compensated circuits.

• Integrated Electronics Options: The DBETE variants feature on-board digital amplifiers, simplifying external wiring and enhancing noise immunity.

• Specialized Environment Adaptation: DBETX/DBETBEX models are specifically designed for explosion-proof or harsh conditions, ensuring safe operation in hazardous areas.

• Superior Dynamic Response: Equipped with precision-ground spools and high-grade spring sets to ensure low hysteresis and exceptional repeatability under frequent adjustment cycles.
