Installation
Introduction
Fluid pressure regulators are used for accurate,
positive control of the fluid pressure to spray guns,
dispensing valves or atomizing heads.
Regulators installed at circulating line take-offs or
pumps are used to reduce main line pressure and
maintain the desired fluid pressure to the spray gun or
atomizing head.
Before Installing the Fluid Regulator
1. Determine where to locate the regulator.
2. Install a ball valve for the regulator inlet and outlet.
3. Install temporary plumbing between the ball
valves.
4. Thoroughly flush the system to remove metal
chips and other contaminants and to check for
leaks.
Installing the Fluid Regulator
1. See Figs. 1 and 2 on page 5. Install one
regulator for each spray gun. Mount the regulator
in a vertical position for the best flow and minimum
pigment settling. The gauge, if used, must be
mounted vertically. If the regulator is mounted
horizontally, an elbow must be used so the gauge
will be vertical.
2. Put sealer on threaded connections, except on
swivel unions as it interferes with the swivel action.
3. Flush and test the entire system. Be sure to follow
the flushing procedure on page 6.
CAUTION
Avoid overtightening threaded connections into the
regulator’s plastic inlet and outlet threads. Check to
be sure the threaded connections are tight and
leak-free, but do not overtighten!
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you
D Are instructed to relieve the pressure
D Stop spraying
D Check or service any of the system equipment
D Install or clean the spray tips
1. Shut off the pump.
2. Close the fluid regulator’s inlet ball valve (B). Refer
to Fig.1, page 5.
3. Relieve fluid pressure in the fluid regulator by
triggering the spray gun.
4. In spring-operated regulators, turn the adjustment
handle (1) counterclockwise until the spring force
is relieved.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely, then clear
the tip or hose.
