GENERAL DESCRIPTION

ARO regulators provide controlled, consistent air pressure

required for the operation of a pneumatic actuated motor and

any coupled system. The integrated ball valve enables the op-

erator to easily throttle the motor/system from an o position

to the preset desired regulator pressure. In turn the operator

can also throttle from a full run position to an off condition

and control the positioning of the motor/system. The ball

valve also enables the operator to safely depressurize the mo-

tor/system without disconnecting the supply air line

CAUTION

High pressure equipment – Always

disconnect air supply and relieve material pressure

before attempting to service.

Ball Valve

1. Move the (8) control handle counterclockwise to pres-

surize the system. A 90 degree movement would be the

“o” position. A 90 – 180 degree movement would allow

the system to be throttled to full regulated line pressure

(180 degree counterclockwise position being the “on”

position) .

2. Move the (8) control handle clockwise to either stop

the system or to de-pressurize the system. A 90 degree

movement would return to the “off” position. A 90 –

180 degree movement would allow the system to be

de-pressurized and vent the residual system pressure

through the (6) vent nut and dump to atmosphere (180

degree clockwise position being “vent” position).

OPERATING AND SAFETY PRECAUTIONS

INSTALLATION

1. Install the 67442 self- relieving ball valve regulator us-

ing the three (11) bolts passing through the (1) regulator

housing. Be certain that the (26) O-ring is in the recess

groove on the mounting side of the (1) regulator hous-

ing to establish the pneumatic seal. Tighten all (11) bolts

evenly to 50-60 in-lbs (13.6-20.3 Nm)

2. The (39) adjustment knob should be turned counter-

clockwise until compression is released from the pressure

control spring. This prevents over pressurizing the air op-

erated equipment when the air supply is turned on .

3. The (8) ball valve control handle should be turned clock-

wise until it stops. This will be in the de-pressurize / vent

position of the control handle. The (8) handle position is

adjustabe to eight dierent locations and can be adjust-

ed by removing the (10) button head screw, (9) washer,

and (8) control handle and oriented as desired. The (7)

key should not be removed. The (7) key establishes the

on/ o /vent orientation of the ball valve.

4. Connect piping to Air inlet port using pipe thread seal-

ant on male threads only. Do not allow sealant to enter

interior of regulator.

5. Air line piping should be the same size as regulator

ports.

OPERATION

Regulator

1. Pull (39) knob to adjust air pressure.

2. Turn clockwise to increase air pressure.

3. Turn counterclockwise to decrease air pressure.

4. Push (39) knob to lock.
