FAQ:

1. What is the core function of the Rexroth 4WRZ series valves?
The 4WRZ series are pilot-operated proportional directional valves designed to precisely control the direction and magnitude of hydraulic fluid flow in industrial systems, actuated by proportional solenoids for proportional spool movement relative to electrical input signals .

2. What are the main components of a 4WRZ series valve?
Key components include a pilot control valve with proportional solenoids, a main valve with a main control spool, centering springs, optional spool position indicator, and an optional manual override .

3. Are 4WRZ valves direct-operated or pilot-operated?
All 4WRZ series valves are pilot-operated (2-stage design), where the pilot control valve regulates the main spool movement .

4. What is the purpose of the manual override on 4WRZ valves?
The optional manual override allows manual adjustment of the control spool without solenoid energization, but caution is required as inadvertent activation may cause uncontrolled machine movements .

5. Do 4WRZ valves have electrical position feedback?
Standard 4WRZ models do not include electrical position feedback; however, some variants (e.g., 4WRZE) may offer integrated electronics (OBE) with additional features .
