FAQ

What is the function of the pilot operation in this valve?

The pilot operation uses system pressure to act on a small internal pilot valve, which in turn controls the main spool. This design allows for more stable and accurate pressure regulation, especially in systems with high flow rates or pressure fluctuations.

What type of hydraulic fluid is compatible with this valve?

This valve is typically designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids, it is essential to check the compatibility of the seal materials.

Can the regulation pressure (Preg) of 80 bar be adjusted?

Yes, the regulation pressure can be adjusted. This is typically done via an adjustment screw, which might be located under a protective cap on the valve body, allowing for precise setting of the downstream pressure required for your application.
