FAQ

Question?

Can I use this ZDR 10 DA2-54/75Y valve on a mounting surface designed for a newer -6X or -7X series valve?

Question?

Yes, the mounting pattern for Rexroth size 10 valves (NG10) conforms to the ISO 4401-05-04-0-05 standard. This ensures interchangeability between different series versions regarding the mounting surface.

Question?

What type of hydraulic fluid is compatible with this valve?

Question?

This valve is typically designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids, such as synthetic esters or water glycols, you should consult the original manufacturer’s datasheet for seal compatibility.

Question?

How do I adjust the reduced pressure setting on this valve?

Question?

The pressure is adjusted by turning the hexagon nut on the end of the spring housing. Loosen the locknut first, then turn the adjustment screw clockwise to increase pressure and counter-clockwise to decrease it. Always use a pressure gauge to verify the setting.
