FAQ

What is the function of the solenoid on this DBW 10 pressure relief valve?

The 24V DC solenoid acts as a pilot unloader. When energized, it vents the pilot stage to the tank, causing the main valve to open at a very low pressure, effectively unloading the hydraulic circuit.

Can the pressure setting of 100 bar be adjusted?

Yes, the pressure setting can be adjusted. The ‘/100’ in the type code indicates the maximum pressure setting for this specific model is 100 bar. The adjustment is typically done via the rotary knob or a concealed screw, depending on the version.

What type of hydraulic fluid is compatible with this valve?

This valve is generally compatible with mineral oil (HL, HLP) based hydraulic fluids according to DIN 51524. For use with other fluids, such as synthetic esters or water glycols, you should consult the official Rexroth datasheet to verify seal compatibility.
