FAQ:

1. Q: What is the recommended filter fineness for the hydraulic system with 4WRZ10?
A: A minimum filter fineness of 10 μm (β10 ≥ 75) is required to protect the valve’s precision components from contamination.

2. Q: Can the 4WRZ10 be mounted in a manifold?
A: Yes, it is compatible with manifold mounting (ISO 4401 manifolds) for space-saving and centralized hydraulic system designs.

3. Q: How to prevent leakage at the hydraulic connections?
A: Use O-rings or flat gaskets (compatible with hydraulic fluid) and ensure proper port cleaning before assembly; avoid over-tightening bolts.

4. Q: What is the correct way to connect the drain port (if applicable)?
A: The drain port (marked “R” or “L”) should be connected to the tank with minimal backpressure (< 3 bar) to ensure proper solenoid cooling and seal lubrication.

5. Q: Does the 4WRZ10 require a bypass valve for startup?
A: A bypass valve is not mandatory but recommended to flush the system before commissioning, removing contaminants that may damage the valve.
