4WRZ10W6-25-7X/6EG24N9TK4/M Proportional hydraulic solenoid directional valve, German Rexroth servo valve

FAQ:

1. Q: Is the 4WRZ10 series a proportional or servo valve?
A: It is a proportional directional control valve, offering precise flow/pressure regulation proportional to the input electrical signal (current or voltage).

2. Q: What is the electrical input signal for the 4WRZ10’s proportional solenoid?
A: The standard input signal is 4-20 mA or 0-10 V DC, with some models supporting dual-coil (push-pull) configurations for enhanced control.

3. Q: Does the 4WRZ10 series have built-in position feedback?
A: Yes, most models feature integrated LVDT (Linear Variable Differential Transformer) or potentiometric position feedback for closed-loop control of the spool position.

4. Q: What is the response time of the 4WRZ10 valve?
A: The typical step response time (from 0 to 100% spool travel) is ≤ 50 ms, ensuring rapid and dynamic control performance.

5. Q: What fluid viscosities are compatible with the 4WRZ10 series?
A: It operates effectively with hydraulic fluids having a viscosity range of 10 to 400 mm²/s (cSt), with an optimal range of 20 to 100 mm²/s.
