Install the valve in the spray gun return line (See the
Typical Installation). Connect the line to the 1 in.
npt(f) inlet and outlet. Make sure flow agrees with IN
and OUT markings on the valve body.
If more than one spray station is used, the back pres-
sure valve should be installed in the supply line after
the last station to maintain proper circulating pressures
in the system.
