FAQ:

1. 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.

2. 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.

3. 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.

4. 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.

5. Q: What is the recommended fluid temperature range for the 4WRZ10?
A: The allowable fluid temperature range is -20°C to +80°C (-4°F to +176°F); extended ranges may be available with special seals.
