Connections
Install the fluid regulator (G) in the spray gun fluid supply line (F), as shown in the typical installation drawings on this page. Connect only one spray gun or dispensing valve to each fluid regulator.
Apply pipe sealant to the male pipe threads, and connect the fluid supply line (F) to the fluid regulator’s 3/8 npt(f) inlet. Connect the line from the gun (J) to the fluid regulator’s 3/8 npt(f) outlet. Install the gauge or plug into the 1/4 npt(f) gauge port.
Make sure the direction of fluid flow agrees with the IN and OUT markings on the regulator body.
Flush the System
The regulator was tested in lightweight oil. Flush the entire system with a solvent compatible with the fluid being dispensed. Then test the system.
Mounting Bracket
A Mounting Bracket is available for mounting the regulator. Order Part 222515 for the bracket and mounting hardware.
