Frequently Asked Questions
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.
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.
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.
What mounting types are available for 4WRZ valves?
Primary mounting is subplate mounting conforming to ISO 4401 porting patterns; flange mounting is also available for select sizes.
What is the difference between 4WRZ and 5WRZ series valves?
5WRZ valves feature an additional "R" port (exclusive to size 52), while 4WRZ valves are 4-port directional valves.
