Rexroth Proportional Valve DBETE-6X/350YG24K31A1V Energy-Saving Low Hysteresis

Product Specification

Description:
The Rexroth Proportional Valve DBETE-6X/350YG24K31A1V is a high-performance industrial hydraulic proportional relief valve designed for precise control of hydraulic system pressure. This valve is a direct-acting proportional valve featuring a cone seat design and an integrated electronic control unit (OBE), enabling seamless adjustment of system pressure based on input electrical signals. It belongs to the 6X series of components, suitable for hydraulic systems with medium to low flow rates. The maximum operating pressure reaches 420 bar, with a pressure setting range of 0 to 350 bar. The maximum flow rate is 2 L/min, meeting the requirements of most industrial applications. Operated by a proportional solenoid, the solenoid is internally connected to the return port (T or Y) and filled with hydraulic oil. This design enables the valve to precisely control hydraulic oil pressure based on input electrical signals, achieving precise regulation of the hydraulic system. Equipped with an integrated electronic control unit, it can precisely control the current of the proportional solenoid valve based on the input electrical signal, thereby achieving precise control of the valve spool position. This enables the valve to achieve stepless regulation, meeting pressure control requirements under different operating conditions.

Advantages:
High-precision pressure control: This proportional valve employs advanced proportional solenoid technology and an integrated electronic control unit to precisely control hydraulic oil pressure based on input electrical signals. Its setpoint pressure characteristic curve has minimal manufacturing tolerances, ensuring stability and consistency under various operating conditions.
Fast response and dynamic performance: Due to its direct-acting design, this valve has a rapid response time, enabling swift adjustment of pressure in response to input signals.
High reliability and durability: The Rexroth Proportional Valve DBETE-6X/350YG24K31A1V is manufactured using high-quality materials, offering excellent wear resistance and contamination resistance. The internal structure of its proportional solenoid has been optimized for long-term stable operation in harsh working environments. Additionally, the valve has excellent sealing performance, effectively preventing hydraulic oil leakage and reducing equipment failures and environmental pollution caused by leaks.
Flexible Installation and Integration: The valve uses a base plate mounting method, with hole patterns compliant with ISO 4401 standards, enabling easy integration into existing hydraulic systems. Its electrical connection methods are flexible, supporting multiple standard electrical interfaces for convenient connection to automated control systems. Furthermore, the valve is equipped with a removable coil for easy maintenance and replacement.
Energy-saving and environmentally friendly: By precisely controlling the pressure and flow of hydraulic oil, this proportional valve avoids unnecessary energy waste and improves the overall efficiency of the hydraulic system.
Excellent linear characteristics: At a flow rate of 0.8 L/min, the valve achieves a linearity of ±3%. This means that within the setpoint range, the valve's output pressure exhibits a good linear relationship with the input signal. This linear characteristic enables the valve to adjust pressure more precisely according to the input signal, meeting control requirements under various operating conditions.
Low hysteresis characteristics: Hysteresis refers to the difference in pressure setpoints when the valve switches between different directions. The hysteresis of the Rexroth Proportional Valve DBETE-6X/350YG24K31A1V is less than 4% of the maximum set pressure.
