A. GATE
The left side of the manifold controls the hose reel. The flow rate is factory set so that the hose reel winds
at a rate of about 13 RPM.
B. AGITATOR
The third valve section controls the speed and rotation of the agitator. The spool in this section is factory
set so that the agitator rotates at approximately 4 RPM. This section also has a pressure switch installed on
the forward port that is set for 2400 PSI (165 bar) that triggers the agitator auto-reverse function. Normal
rotation of the agitator is clockwise if looking from the rear of the machine.
C. DRAG CONVEYOR FLOOR & FEED ROLL
The fourth valve from the left, controls the floor and feed roll speed. It is an electrically-driven proportional
valve that is controlled by the floor speed settings on the control box. Adjusting the dial from 0 to 100 varies
the input voltage to the solenoid and moves the spool in the valve accordingly, allowing more or less oil flow
to the floor and feed roll. The feed roll is plumbed in series with the floor, meaning oil flows to the feed roll
motor first and then down to the floor motors. This setup automatically causes the floor to slow down if the
feed roll begins to jam up, preventing overfeeding of the feed roll.
D. ROTARY AIR VALVE (AIRLOCK)
T
he last valve section of the manifold runs the airlock. The spool in the valve is factory set so that the
airlock turns at about 12 RPM. The proportional valve, in combination with the control box, provides ad-
justment of the airlock speed. There is a pressure switch on the forward circuit that is set for 2400 PSI (165
bar) that triggers the auto-reverse function on the airlock. Normal rotation of the airlock is clockwise if
looking from the driver side of the machine.
