Frequently Asked Questions
Can 4WRZ valves handle pressure spikes?
They are rated for maximum operating pressure (315-350 bar) but should be protected with pressure relief valves to prevent damage from excessive spikes.
What is the recommended maintenance interval for 4WRZ valves?
Routine inspection every 6 months; maintenance frequency increases with harsh operating conditions (e.g., high temperature, dirty fluid).
How to replace the seal kit on a 4WRZ valve?
Disassemble the valve per the manual, remove old seals, clean seal grooves, install new seals (NBR or FKM, per fluid compatibility), and reassemble.
What spare parts are commonly required for 4WRZ valves?
Seal kits (valve connection surface and terminal box), detachable solenoid coils, centering springs, and manual override components.
How to clean a 4WRZ valve?
Flush the valve with compatible hydraulic fluid; remove and clean the main spool if jamming occurs (avoid abrasive cleaners).
