STEP 6
Actuate the solenoid to open the main valve, checking that the
main valve opens.
Step 7
Slowly open downstream isolation valve to establish flow through
the system.
Counterclockwise to DECREASE
downstream pressure
Clockwise to INCREASE-
downstream pressure
Step 9
Opening Speed Flow Control Adjustment: The Opening speed
flow control allows free flow into the cover and restricted flow out
of the cover of the main valve. If recovery of pressure is slow upon
increased downstream demand, turn the adjustment screw OUT,
counterclockwise, increasing the rate of opening. IF recovery of
downstream pressure is too quick, as indicated in a rapid increase
in pressure, possibly higher than the desired set-point, turn the
adjustment screw IN, clockwise, decreasing the rate of opening
(See Figure 3).
Step 8
Fine-tune the Pressure Reducing Control adjustment to the
desired pressure set point by turning the adjustment screw IN,
clockwise to increase or OUT, counterclockwise to decrease
downstream pressure (See Figure 2).
Counterclockwise to INCREASE
the rate of opening
