German original Rexroth proportional valve R900955784 3DREPE6C - 21/25EG24N9K31/A1M

1. Product Overview

This is a product made byRexrothProductionHigh-frequency response direct-acting proportional relief valveThis valve integratesElectronic amplifier (OBE)It can steplessly and continuously adjust the hydraulic system using analog electrical signals (such as 0-10V or 4-20mA).Maximum working pressureIt possessesHigh dynamic responseandPrecise pressure control characteristicsIt is an ideal alternative to traditional manually adjustable relief valves and complex hydraulic pilot circuits.

2. Core Features

• High frequency response and high precisionIt adopts a proportional electromagnet to directly drive the valve core, which has an extremely fast response speed and can quickly build up or release pressure, making it very suitable for closed-loop control loops that require frequent start-stop or rapid pressure switching.

  
  

• Integrated Electronic Amplifier (OBE)The built-in amplifier simplifies external wiring, reduces electromagnetic interference, and facilitates the setting of valve zero point and gain, thereby improving system stability and reliability.

  
  

• Stepless pressure regulationBy adjusting the magnitude of the input signal, the pressure can be adjusted arbitrarily from zero to the maximum set pressure, with smooth control and no noticeable step difference.

  
  

• Compact structureThe valve body is designed to meet NG6 standards, with a compact structure that facilitates integration into valve blocks or compact hydraulic systems.

  
  

3. Typical Applications

• Injection molding machineUsed for precise control of injection pressure, holding pressure, and clamping force.

  
  

• pressUsed for multi-stage pressure control in processes such as metal forming and powder metallurgy.

  
  

• Test benchUsed for pressure loading control in fatigue testing and pressure resistance testing of hydraulic components or materials.

  
  

• machine tool: Used for pressure control and balancing circuits in hydraulic clamping systems.
