Product Description
DBETBX / DBET Series Precision Direct-Operated Proportional Relief Valves
Product Overview: The Rexroth DBET series represents the core solution for remote, stepless pressure regulation in industrial hydraulic systems. As direct-operated proportional relief valves, they utilize a proportional solenoid to actuate the poppet directly, linearly converting electrical input (current) into hydraulic set pressure. The DBETBX sub-series enhances dynamic response and is frequently used in closed-loop control circuits or as a pilot stage where high precision and repeatability are critical.
Featured models include: 811402003 (DBETBX-1X/180G24-37Z4M) and the specialized DBET-A0/140-995-0.
Key Technical Advantages:
High-Precision Linear Regulation: The synergy between the proportional solenoid and poppet design ensures minimal hysteresis and excellent linearity across the entire pressure range (up to 180 bar).
Compact Direct-Acting Design: The simplified structure offers rapid response times, effectively protecting systems from instantaneous overpressure while ensuring smooth unloading and pressure build-up.
Industrial-Grade Solenoids: Equipped with G24 (24V DC) high-performance coils, engineered for long service life, high-frequency operation, and 100% ED (Continuous Duty).
Application-Specific Customization: The DBETBX version is optimized for specific industrial standards (e.g., 37Z4M interface), ensuring seamless integration with high-end machine tools and automated production lines.
