Operation
Adjusting the Regulator Outlet Pressure
WARNING
To reduce the risk of serious injury, never remove
the adjusting screw or diaphragm housing when the
valve is under pressure.
For a spring-operated regulator, turn the adjusting
screw (6) counterclockwise to decrease and clockwise
to increase pressure to the spray gun or extruder gun.
For an air-operated regulator, adjust the air regulator
on top of the diaphragm (or other upstream air regula-
tion device), to adjust the downstream fluid pressure
up or down. See the chart at right for air vs. fluid
pressure.
Adjust the pump air pressure and the mastic regulator
pressure for the best dispensing combination. For the
optimum performance, the inbound fluid pressure
should be at least 600 psi (4.1 MPa, 41 bar) above the
regulated fluid pressure.
NOTE: When using a fluid pressure gauge in the
regulator outlet, partially relieve pressure by triggering
the gun while reducing the regulator pressure. This
helps ensure a correct gauge reading. For high accura-
cy applications, add a C06234 bleed fitting. This ad-
justable flow control replaces an outlet plug in the
regulator. This allows the air regulator to hold a more
accurate set point. Model C58318 comes with this
bleed valve.
NOTE: Model 244740 is equipped with inlet and outlet
pressure sensor ports. Pressure Sensor Kit 198082
can be used to monitor inlet and/or outlet pressures.
This chart shows the approximate air pressure needed
to regulate the air-operated regulator to a given fluid
outlet pressure.
