Operating priority flow valve I*

Priority flow valve I is used to drive the servo motor in an

attachment with a variable hydraulic power demand, for

example, salt spreader, hedge cutter, etc. The working speed

can be set independently of the tractor engine speed. The

priority flow valve is fed by the (standard) working pump

and operated from the driver’s station.

- Connect the hydraulic hoses of the attachment to the

red quick couplings for the drive (1) and return line (2)

at the front of the vehicle.

lics.
