Air Line Modules
WARNING
PRESSURIZED FLUID HAZARD AND
MOVING PARTS HAZARD
The bleed-type master air valve (C) is
required in your system to relieve air
trapped between this valve and the
pump after the pump air regulator is
closed. Trapped air can cause the pump
to cycle unexpectedly, which could result
in serious bodily injury, including splashing in the
eyes or on the skin and injury from moving parts.
4-Regulator Air Control Modules (918–425) (shown)
See the Typical Installation drawing (Fig. 1) and Fig. 2.
The following components are included with the mod-
ule:
D
Bleed-type Lock-out Master Air Valve (B) is used to
shut off and lock out the air supply from the entire
supply unit.
D
Pump Bleed-type Master Air Valve (C) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
Pressurized Fluid Hazard And Moving Parts
Hazard WARNING above). This bleed valve
should be easily accessible and located down-
stream from the air regulator. It can be used for a
safety lockout.

Pump Air Regulator (D) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. It is located on the air control panel up-
stream from the bleed-type master air valve.
D
Ram Air Regulators (O) control the air pressure to
the hydraulic power supply that controls ram move-
ment. There are separate air regulators to control
the ram pressure in the up and down directions.
D
Hydraulic Power Supply (X) controls the ram’s
movement.
D
Follower Blow-off Valve (N) controls the air pres-
sure to the follower blow-off.
D
FRL (filter, regulator, lubricator) (A), (D), and (I)
conditions the air to the ram and the pump. The
pump air regulator is located in this assembly. The
ram air is taken from this assembly; an air line tube
connects the FRL and the ram air control module.
Air Line Accessories
D
Pump runaway valve senses when the pump is
running too fast and automatically shuts off the air
to the motor. A pump that runs too fast can be
seriously damaged.
D
Accessory bleed-type air valve isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories. This isolates the acces-
sories for servicing.
Vent Hood Kit
The vent hood assembly is designed to efficiently draw
fumes to the factory exhaust system during drum
change-out. This assembly requires connection to a
factory ventilation system that draws a minimum air
flow of 8.4 m
3
/min (300 scfm). This kit is required for
Polyurethane Reactive (PUR) applications.
Hydraulic Power Supply Module
The hydraulic power supply module delivers up to
39 liters per minute (10 gpm) at 66 cycles per minute
for moving the ram cylinder rods.
