FAQ

Question? What is the significance of the "Y" in the model number ZDR 10 DA2-54/75Y?

The "Y" indicates an external pilot oil drain. This configuration is necessary in systems where pressure in the return line (port T) can exceed the pressure being set at port A, ensuring proper valve function by draining pilot oil to a separate, low-pressure tank line.

Yes, 75 bar is the maximum pressure setting for this specific model. The valve is adjustable via the rotary knob, allowing you to set any pressure between the minimum setting (approx. 5 bar) and the maximum of 75 bar.

For optimal performance and a long service life, Bosch Rexroth recommends a hydraulic fluid cleanliness class of at least 20/18/15 according to ISO 4406. Using cleaner fluid will further extend the valve's life.
