General Description
A complete range of Binks low shear back pressure regulators are available to suit
most pressure and technical requirements for paint circulating systems.
This equipment is designed for use with Solvent based and Waterborne materials.
Suitable for use in Zone 1 and 2, Protection Level: II 2 G X
Model Ideal Working Range Max Static
Pressure
Wetted Materials
502742 - Pilot 1-15 Bar 2 – 30 L/min 25 Bar Stainless Steel
This ¾ model is extremely flushable as no gauge ports passages are drilled into
the body to create ‘dead’ areas.
The Binks low shear back pressure regulators adjust to control the paint system
back pressure within the pipe line and minimises ‘paint shear’ due to the large
surface area of the valve seating.
The ‘back pressure’ regulator responds to the changes in system fluid pressure,
(due to variable paint usage) by dynamically adjusting to maintain the set
pressure, thus maintaining the required system back pressure.
If the pressure in the system drops below the regulated level (system demand
exceeds pump supply rate) then the valve will close.

Equipment Misuse Hazard
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
• This equipment is for professional use only.
• Read al l instruction manuals, tags, and labels before operating the equipment.
• Use the equipment only for i ts intended purpose.
• Do not alter or modify this equipment. Use only genuine Binks PCE parts and accessories.
• Check equipment dai ly. Repair or replace worn or damaged parts immediately.
• Do not exceed the maximum working pressure stated on the equipment or in the Technical Data for your
equipment. Do not exceed the maximum working pressure of the lowest rated component in your system.
• Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Technical Data
section of al l equipment manuals. Read the fluid and solvent manufacturer’s warnings.
• Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose hoses to
temperatures above 82°C (180°F) or below —40°C (—40°F).
• Do not l i ft pressurized equipment.
• Comply with al l appl icable local, state, and national fi re, electrical , and safety regulations.
Fire, Explosion and Electric Shock Hazard
Improper grounding, poor venti lation, open flames or sparks can cause a hazardous condition and result in a fi re,
explosion, or electric shock.
When installed and operated in accordance with i ts instructions, the pump is approved for operation in Zone 1
(Europe) & Division 1 (North America), hazardous locations. (ATEX Cat 2)
• Electrical equipment must be instal led, operated, and serviced only by trained, qual ified personnel who ful ly
understand the requirements stated in this instruction manual.
• Ground the equipment and al l other electrically conductive objects in the spray area. After grounding test with
ohmmeter to ensure earth continuity is 1 ohm or less.
• Keep all covers tight while the motor is energized.
• If there is any static sparking or you feel an electric shock while using this equipment, stop spraying/dispensing
immediately. Do not use the equipment until you identify and correct the problem.
• Provide fresh air venti lation to avoid the bui ld up of flammable fumes from solvents or the fluid being
pumped.
• Keep the pumping area free of debris, including solvent, rags, and gasoline.
• Electrical ly disconnect al l equipment in the pumping area.
• Extinguish al l open flames or pi lot l ights in the spray/dispense area.
• Do not smoke in the spray/dispense area.
• Do not turn on or off any l ight switch in the spray/dispense area whi le operating or if fumes are present.

WARNING
KEEP EQUIPMENT GUARDS IN PLACE
Do not operate the equipment if the safety
devices have been removed.
READ THE MANUAL
Before operating equipment, read and
understand all safety, operation and
maintenance information provided in the
operation manual.
DE-ENERGIZE, DEPRESSURIZE, DISCONNECT
AND LOCK OUT ALL POWER SOURCES DURING
MAINTENANCE
Fai lure to De-energize, disconnect and lock out
a l l power supplies before performing
equipment maintenance could cause serious
injury or death.
OPERATOR TRAINING
All personnel must be trained before
operating equipment.
PROJECTILE HAZARD
You may be injured by venting liquids or
gases that are released under pressure, or
flying debris.
PINCH POINT HAZARD
Moving parts can crush and cut. Pinch
points are basically any areas where there
are moving parts.
WEAR SAFETY GLASSES
Fai lure to wear safety glasses with side
shields could result in serious eye injury or
bl indness
NOISE HAZARD
You may be injured by loud noise. Hearing
protection may be required when using this
equipment.
KNOW WHERE AND HOW TO SHUT OFF THE
EQUIPMENT IN CASE OF AN EMERGENCY
HIGH PRESSURE CONSIDERATION
High pressure can cause serious injury. Relieve
a l l pressure before servicing. Hose leaks, or
ruptured components can inject fluid into your
body and cause extremely serious injury.
AUTOMATIC EQUIPMENT
Automatic equipment may start suddenly
without warning.
PROP 65 WARNING
WARNING: This product contains chemicals
known to the State of California to cause
cancer and birth defects or other
reproductive harm.

MAGNETIC FIELD PRESENT
You may be subjected to magnetic fields
which may interfere with the operation of
certa in pacemakers.
MAGNET HAZARD
Take care when handling magnets.
Avoid getting magnets in close proximity of
each other. Injury or damage to magnets
may results.

Installation - Mounting
1. Connect the unit into the paint system pipework; either port can be used as the
inlet connection. Connection ports are ¾ NPT
2. Always connect the unit using the correct fittings and a suitable thread sealant
that is compatible with the fluids passing through the valve.
3. A pressure gauge should be mounted directly into the pipework on the inlet
side of the unit to allow precise adjustment for the regulated back pressure.
Installation – Setting to work
The Back pressure regulator is tested with demineralised water, therefore the fluid
chamber should be flushed with suitable material prior to use.
Note: Before attempting any maintenance ensure that all relevant directions for
working safety are followed.
1. If circulating system pressure testing is carried out with the back pressure
regulator in circuit, the fluid test pressure must not exceed 25 Bar and the
back pressure valve must ‘be unloaded’ have no air pressure acting on the
diaphragm.
2. When the paint pipework is to be flushed with the back pressure regulator
installed, the back pressure regulator must not have any air pressure acting
on the diaphragm. This status must remain until the paint system has been
accepted as clean and contaminant free.
3. Following pressure testing and flushing procedures the diaphragms should be
examined and replaced if necessary to ensure the integrity of the unit prior to
use in production.
4. Adjust pilot air pressure until the desired system fluid back pressure is
achieved on the pressure gauge in the BPR inlet pipework.
