Installation
Fluid pressure regulators are used for accurate, posi-
tive control of the fluid pressure to spray guns, dis-
pensing 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,
dispensing valve, or atomizing head.
Before Installing the Fluid Regulator
1. Determine placement of the fluid regulator in
system.
2. Install a ball valve for inlet and outlet of the regula-
tor.
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. Remove the temporary plumbing and install one
regulator for each spray gun. A mounting stud,
washers, and locknut are provided for mounting
the regulator either from the bottom or side.
2. Put sealer on threaded connections, except on
swivel unions as it interferes with the swivel action.
3. Connect the fluid supply line to the 3/8 npt(f) inlet
of the fluid regulator. Connect the fluid line be-
tween the gun and the regulator’s 1/4 npt(f) outlet
of choice. MAKE SURE that the direction of fluid
flow agrees with the IN and OUT markings on the
regulator body.
4. Flush and test the entire system.
