DBETBEX-1X/250G24K31A1M DBETBEX-1X/250G24K31A1M-42 DBETBEX-1X/250G24K31A1V DBETBEX-1X/250G24K31F1M Rexroth direct acting proportional relief valve integrated position control imported from Germany

The DBETBEX-1X series proportional relief valves are direct-acting, electrically controlled pressure control valves with integrated position feedback and built-in electronics. These valves provide precise proportional pressure regulation with minimal hysteresis, designed for demanding industrial hydraulic applications requiring high accuracy and fast response.

• Integrated Electronics: Built-in control electronics with K31 connection for simplified system integration
• Position Feedback: Integrated LVDT for closed-loop control with high accuracy
• Direct-Acting Design: Cone valve structure for fast response and precise pressure control
• Proportional Control: 0-10V or 4-20mA input signal for continuous pressure adjustment
• Low Hysteresis: Typically less than 0.2% of full scale with closed-loop control
• Standard Mounting: ISO 4401-03-02-0-05 interface
• Seal Options: NBR (A1) for mineral oils, FKM (F1) for special fluids
• Performance Options: M (standard) and V (enhanced) versions
• Option Codes: -42 suffix for enhanced diagnostics
• Environmental Protection: IP65 rating standard
• Pressure Rating: 250 bar maximum pressure

The -42 suffix typically indicates enhanced diagnostic features or additional monitoring capabilities. This may include built-in sensors for condition monitoring, extended diagnostic functions, or additional feedback signals. The exact features should be verified in the product documentation.

A1 refers to NBR (Nitrile) seals, which are standard for mineral-based hydraulic oils and offer good general-purpose performance. F1 refers to FKM (Fluorocarbon) seals, which provide superior chemical resistance and are suitable for phosphate ester fluids, HFD fluids, and other aggressive hydraulic media. Always confirm seal compatibility with your specific fluid.

With integrated electronics and closed-loop control, DBETBEX series valves typically achieve 90% of set pressure within 30-50ms under standard conditions. The V (enhanced) versions may offer faster response times. Actual performance depends on system conditions and should be verified in the product data sheet.

Yes, the integrated electronics in the K31 connection typically support both 0-10V and 4-20mA input signals. However, the specific signal type may need to be configured or selected during installation. Always refer to the product documentation for signal compatibility and configuration requirements.

Standard models with NBR (A1) seals are rated for operation between -20°C to +80°C. For FKM (F1) seals, the temperature range may be slightly different. The hydraulic fluid temperature should typically be maintained between 20°C and 50°C for optimal performance. Always check the product data sheet for specific temperature ratings.

All models are available through authorized distribution channels. When ordering, please provide the complete model number including all suffixes. Standard delivery time is 6-8 weeks for standard configurations. Custom options may require additional lead time.
