Hydraulic Controllers control the hydraulic pilot pressure
required to operate hydraulic remote, spool actuated,
directional control valves. Each remotely located
Controller provides spool positioning for precise control
Remote operation, low flow, and low pilot pressure...all
mean less noise in the operator compartment or at the
The design of the Hydraulic Controllers is based on the
pressure reducing valve principle...pilot pressure is
varied proportionately with the lever stroke. Because of
low pressure in the pilot line (500 PSI [34,5 bar]),
resistance to movement of the controller handle is much
lower than that required for mechanical linkage or for
handles mounted directly on the control valve.
Model HCJ - Joystick Type Controllers provide
remote hydraulic control for two directional control valve
work sections simultaneously. It is ideal for armrest
mounting because of its low "handle effort". An optional
pistol grip handle with thumb switch is available for
controlling an ON-OFF solenoid-operated control valve
simultaneously with the two hydraulic remote functions.
The handle movement from neutral to full power is 19°
to 24° in a 360° rotation.
Model HCS - Sectional Type Controllers provide
control for a single directional control valve work.
section. Model HCS Controllers may be used singly or
stacked into multiple sections with studs and section
seals. The handle movement from neutral to full power
is 19°, forward and backward only
maximum comfort and control for the operator. The
treadle has both raised cleats and heel lip to reduce foot
slippage. A light heel or toe force controls pilot pressure
from 0 to 500 PSI [34,5 bar]. A 19° travel of heel or toe
provides full pilot pressure at each control port.
The Model HCF will mount flush with the floor of the
operator compartment. All hydraulic connections are
below the floor and out of the way. The HCF's low
profile eliminates unnecessary and potentially unsafe

lubrication to minimize wear and increase trouble-free
