Single Direct Spray Station

Install the fluid regulator(s) (G) in the spray gun fluid supply
line (F) as shown in the Typical Installation drawing above or
at right. Connect only one spray gun or dispensing valve to
each fluid regulator.
Using pipe sealant on pipe threads, connect the fluid supply
line (F) to the fluid regulator’s 1/4 npt(f) inlet. Connect the line
from the gun (J) to the regulator’s 1/4 npt(f) outlet.
Make sure the direction of fluid flow agrees with the IN and
OUT markings on the regulator body.
The regulator was tested in lightweight oil. Flush the entire
system with a solvent compatible with the fluid being sprayed
or dispensed, then test the system.
