REMOTE HYDRAULIC CONTROL SYSTEM
The hydraulic auxiliary control valves can be installed up
to quartet segments.
BRemote Control Valve
There are 2 types of remote valves available for these
models.
A Double acting valve with detents and self cancelling:
This valve may be placed in the detent mode. The
lever will stay in this position until the pressure reaches
a predetermined level or a cylinder reaches the end of
its stroke. Then it will automatically return to neutral
A Double acting valve with float position:
This valve may be placed in the float mode with the
control lever all the way forward. The cylinder is free to
extend or retract, letting an implement such as a
loader bucket follow the ground.
BRemote Control Valve Lever
The remote control valve lever directs pressurized oil flow
to the implement hydraulic system.
