 GENERAL MAINTENANCE

PROPORTIONAL VALVE

Automizer

TM

 units use an extra valve stack

to control the arm, the chute and the crusher
panel (if equipped) (Figure #1.80). This
valve is on/off or proportional type, meaning
that the amount of flow coming out of it will
be according to the position of the spool.

This feature (proportional control) allows
infinite control of the speed and the
movement of the arm. The arm is powered
by a dual vane pump (see 

section 1.14.9

“Dual Vane Pump”).

Each section of the valve is actuated by an
electrical coil, located under the valve. The
proportional valve sections are described as
follow from top to bottom on figure #1.81.

VALVE  SECTION  DESCRIPTION:

• Input/Output cover:

(Provided with main relief valve)

• Crusher panel section (optional; not

shown):
(Not proportional, with load sense relief)

• Grabber section (Open/Close):

(Not proportional, with load sense  relief)

• Grabber section (Up/Down):

(Proportional, no load sense relief)

• Telescopic arm  section (Extend/
