"REXROTH" CONTROL VALVES (PILOT MODELS)

The loader backhoe with hydraulic control (pilot mod-
els) differs basically from the mechanical loader
backhoe models for the reason that the controls driv-
ing the loader attachment and the stabilizers are hy-
draulic instead of being mechanical. By means of the
control levers located in the cab a control valve is
driven, that on its turn drives hydraulically the back-
hoe control valve, monitoring the backhoe loader
and the stabilizers.
The backhoe loader with hydraulic control is
equipped with two control valves:
Z Loader control valve: mounted on the right hand
side of the backhoe loader and provides oil flow to
the loader boom and front bucket.
Z Backhoe control valve: located in the rear part of
the chassis, it provides the oil flow to the backhoe
attachment, to the stabilizers and to the backhoe
bucket.
