Frequently Asked Questions
1. What is the 4WRA6 valve?
The 4WRA6 is a series of direct-operated proportional directional valves manufactured by REXROTH. It is designed as a subplate-mounted component and is typically used to control both the direction and flow rate of hydraulic fluid in a system, thereby managing the direction and speed of hydraulic actuators.
2. What are the main features of the 4WRA6 series?
  • Direct-Operated Design: The valve spool is moved directly by proportional solenoids without the need for a pilot pressure stage.
  • Spring-Centered Spool: When the solenoids are de-energized, the spool returns to and is maintained in the center position by compression springs.
  • Mounting: Subplate mounting with porting interface according to ISO 4401.
  • Two Configurations: Available with external control electronics (4WRA type) or with integrated onboard electronics (OBE) (4WRAE type).
  • Flow Control: Provides proportional flow control with a progressive flow characteristic (metering notch) in addition to direction control.
3. What is the difference between 4WRA and 4WRAE?
The key difference lies in the location of the control electronics.
  • 4WRA: Requires an external, separate amplifier to function. The amplifier processes the input signal (e.g., from a PLC) and provides the necessary power to the valve's solenoids.
  • 4WRAE: Features Integrated OnBoard Electronics (OBE). The control electronics are built into the valve, allowing it to accept standard analog input signals (e.g., ±10 V or 4-20 mA) directly.
4. How do I read the model number?
A typical 4WRA6 model code is structured as follows:
  • 4WRA: Series designation for proportional directional valve without OBE. "E" after WRA (4WRAE) indicates integrated electronics.
  • 6: Nominal size (06). Alternative size is 10.
  • W / E / etc.: Spool symbol/type (e.g., W, E, EA), which defines the flow characteristics and center position condition.
  • 07 / 15 / 30: Nominal flow rate in liters per minute at a pressure drop (Δp) of 10 bar. For size 06, common values are 7, 15, or 26/30 L/min.
  • 2X: Component series (20-29).
  • G24: Supply voltage (24 V DC).
  • K4 / K31: Electrical connection type (e.g., without plug, with specific component socket).
  • V: Seal material (e.g., FKM for mineral oil).
  • A1 / F1 (for 4WRAE): Control value input type (A1 for ±10V, F1 for 4-20mA).
5. What are the key technical specifications?
  • Maximum Operating Pressure: Up to 350 bar for P, A, B ports.
  • Maximum Flow: Varies with model (e.g., 42 L/min for some 4WRAE6 models).
  • Recommended Fluid Cleanliness: ISO 4406 20/18/15.
  • Voltage: Typically 24 V DC.
6. What are common applications for the 4WRA6 valve?
These valves are used in various industrial hydraulic systems requiring precise control, such as:
  • Plastic injection molding machines.
  • Presses and bending machines.
  • Mobile equipment.
  • Industrial automation systems where proportional control of speed and direction is needed.
7. What are common troubleshooting issues?
Common problems and their potential causes include:
  • Valve does not shift or responds slowly: Check solenoid coil for burnout or open circuit; check power supply voltage; check for contamination causing the spool to stick.
  • Internal Leakage: Worn spool or seals, or contamination causing improper sealing.
  • Valve sticking: Often due to inadequate fluid cleanliness, insufficient lubrication, or internal damage.
  • Excessive noise: Can be caused by excessive vibration, voltage fluctuations, or issues with the solenoid.
  • No function despite signal: Check the amplifier (for 4WRA), wiring, and connections between the control unit and the valve.
8. What maintenance is required?
  • Regularly check the solenoid coils and valve spool for wear.
  • Maintain fluid cleanliness to prevent contamination, which is a primary cause of valve failure. Ensure the filtration system is functioning properly.
  • Periodically inspect electrical connections and seals.
