OPERATING AND SAFETY PRECAUTIONS
EXCESSIVE AIR PRESSURE
STATIC SPARK
Read and heed all warnings, cautions and safety pre-
cautions before operation of this unit.
Be certain anyone operating this equipment or fluid
system has been trained to use it safely.
WARNING
HIGH PRESSURE DEVICE. Improper usage of
this equipment could result in serious injury. The possibility of injection into the esh is a potential hazard.
Wear approved safety glasses or face shield and other
equipment as needed to prevent injury. Never allow any part of the human body to come in front of
or in contact with the material outlet, the tip, or the
material outlet of the dispensing device. An injection
injury can be serious. If an injection accident should
occur, it is very important that you contact a quali ed
physician for immediate treatment.
WARNING
MISAPPLICATION HAZARD. Do not use the
regulator when the uid inlet pressure is too high for
the designed operating range. Excessive inlet pressure can cause a lock-out situation. Lock-out occurs
when the inlet pressure is beyond the regulator’s
spring capacity. The valve will not open. Attempts to
disassemble components while in a lock-out condition may result in injury.
WARNING
COMPONENT RUPTURE. Do not operate
regulator at an inlet pressure greater than speci ed.
To avoid possible damage or personal injury do not
operate this unit at pressure higher than the stated
operating range as it appears on the model plate.
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING
DISASSEMBLY HAZARD. Do not disassemble
this regulator when it is under pressure. Relieve pressure in the pumping system before attempting service
or disassembly procedures. Disconnect air lines and
carefully bleed pressure o the system. Be certain the
system is not maintaining pressure due to a material
restriction in the hose, line, dispensing device, or the
spray or extrusion tip. Failure to relieve pressure both
up stream and downstream may result in an injury
upon disassembly.
WARNING
BONNET REMOVAL HAZARD. Do not attempt to remove the four bonnet retaining bolts
without rst relieving the tension on the main spring.
Failure to relieve tension could result in an accident
upon disassembly.
WARNING
PREVENT FIRES. Keep solvents away from
heat, sparks or open flame. Keep containers closed
when not in use. When pumping, flushing or recirculating volatile solvents, be certain the area is adequately ventilated.
CAUTION
FLUSH SUPPLY LINE. Before installing uid
regulator blow the supply lines clear and ush to remove contaminates.
WARNING
= Hazards or unsafe practices which
could result in severe personal injury,
death or substantial property damage.
CAUTION
= Hazards or unsafe practices which
could result in minor personal injury,
product or property damage.
NOTICE
= Important installation, operation or
maintenance information.
INSTALLATION
Refer to the typical installation view which best applies.
Locate the regulator as close as possible to the spray gun
or dispensing device for best pressure control.
Identify the regulator INLET / OUTLET (flow direction).
The regulator is marked with an arrow on the body base
(refer to gure 10).
When flexible fluid lines are used, mount the regulator
securely using the (2) 1/4” - 20 threaded holes in the base
(see gure 10).
Flush supply line before installing regulator.
Remote models require maximum 100 p.s.i. (6.9 bar)
signal pressure. Start with a signal pressure as low as possible and adjust upward until proper ow is reached.

OPERATING INSTRUCTIONS
TROUBLE SHOOTING
Refer to pages 4 and 5 for parts reference.
To INCREASE outlet pressure, turn the (6) adjusting screw
CLOCKWISE (see gure 3).
To DECREASE outlet pressure, turn the (6) adjusting
screw COUNTERCLOCKWISE (see gure 3).
NOTE: Part Y106-109 Allen wrench is included to make necessary pressure adjustments.
FLUSH-OUT FEATURE FOR DOWNSTREAM MODELS ONLY.
See gure 4.
Flush the regulator periodically. The interval may vary de-
pending on the amount and type of material used.
By using a wrench and “flush-out” plug (provided), the
operator is able to move the entire spindle downward
and force the ball off the seat which should purge the
regulator of particle build-up.
NOTE: The flush-out procedure temporarily overrides the
adjusted pressure. It will not, however, affect the regulator
setting when ushing operation is completed.
FLUSH-OUT PROCEDURE
Remove spray gun or dispensing device, this will allow
1.
any particles to clear from the system.
Insert (21) flush-out plug and turn clockwise until it
2.
touches the (4) washer (see view on page 5).
Turn up to two turns maximum. This will allow the ball to
3.
unseat and pass material at free ow (unregulated). DO
NOT attempt to turn further to avoid damage.
Turn the plug back to its original position.
4.
No uid pressure.
Check for damaged or worn diaphragms.
Look for possible obstruction by hardened material or
foreign matter, periodically use the regulator “Flush-out”
feature (Downstream models only). Use a uid lter upstream from the regulator.
Pressure creeps above the setting when system is
dead ended and in a static (no ow) mode.
Check for dirty seat and clean as appropriate.
Check for worn or damaged seat and replace if necessary.
Outlet pressure drops below setting.
Check pump for proper operation and check for possible
leakage problems.
Look for a clogged supply line problem, ush the supply
line.
Fluid leakage from spring housing.
Check the bonnet hold-down screws and the plate hold
down screws and re-torque as needed.
Check for damaged diaphragm, replace as needed.
Regulator will not function, even when dispensing device is opened.
Check for possible obstruction in the uid line.
Inlet pressure is too high, causing a “Lock-Out” situation.
Read “WARNING: MISAPPLICATION HAZARD” found on
page 2.
SEAT PLUG FEATURE
The (47) plug, located at the base of the regulator, can be
removed for access to the ball and seat assembly for cleaning and inspection for wear. With this feature, the regulator
does not have to be unthreaded from the pumping system.
Be certain to relieve system pressure (See “WARNING: DISASSEMBLY HAZARD”).
MAINTENANCE
Disassembly should be done on a clean work bench and
use clean cloths.
If replacement parts are necessary, refer to the parts list
and drawings on pages 4 and 5.
Upon reassembly, lubricate parts and use Loctite where
indicated. Follow the torque speci cations as shown.
Service kits are available, which include parts typically
needed for an overhaul.
Keep good records of service activity and include the
regulator in a preventive maintenance program.
Certain “Smart Parts” are indicated with a “
list, these parts should be available for fast repair and re-
duction of down time.
