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 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. Remove the temporary plumbing and install one
regulator for each spray gun. See the Dimension-
al Drawing on page 21 for regulator dimensions.
Mount the regulator in a vertical position, as shown
in Figs. 1 and 2, 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 the
swiveling end of 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 8.
