General Information
NOTES:
D Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and the
parts drawing.
D The Typical Installation shows a typical dead-end
hookup. Regulators should be mounted close to the
dispense point. The whip hose and nozzle must
provide enough back pressure to stay within the
adjustable range of the regulator. The majority of
this restriction should be provided by the nozzle, to
prevent static head pressure from increasing when
the valve closes.
The regulators have one 3/4 npt(f) inlet port and two
3/4 npt(f) outlet ports for straight through or right angle
flow. Install one regulator upstream from each gun on
the line. A fluid pressure gauge can be installed in the
second outlet port for precise monitoring of outlet
pressure. Plug the port when not in use. See the
Typical Installation, above, and the Dimensions
section on page 30.
WARNING
When the second outlet port is not used, it must be
plugged with a steel plug, supplied, to prevent high
pressure fluid from being emitted from the port.
High pressure fluid can cause serious injury.
For an air-operated regulator, connect a grounded air
supply hose to the 1/4 npt(m) adapter at the inlet of the
air regulator.
Conversion Kit Installation
1. To relieve fluid pressure, shut off the power to the
pump, trigger the gun to relieve pressure, and
open any system bleed or drain valves. Remove
the regulator from the line.
2. If installing a new spring, unscrew and remove the
adjusting screw (6) and spring (9). Install the new
spring and reinstall the screw.
3. If converting to an air-operated regulator, unscrew
and remove the adjusting screw (6), spring (9),
and spring guide (11) from the valve cylinder (7).
Apply lubricant to the threads of the conversion kit
diaphragm housing (101). Screw the housing into
the valve cylinder, torque to 20 in-lb (2.25 NSm).
