STEP 6
While reading the meter register, adjust the Rate of Flow Control:
Turn the adjustment screw IN, clockwise, to increase the flow rate
regulated (See Figure 2A).
Turn the adjustment screw OUT, counterclockwise, to reduce or
lower the flow rate regulated (See Figure 2B).

STEP 7
Fine tune the Pressure Reducing Control to the desired pres-
sure set point by turning the adjustment screw IN, clockwise to
increase (See Figure 3A) or OUT, counterclockwise to decrease
(See Figure 3B) downstream pressure.
STEP 8
Closing Speed Needle Valve Adjustment: The closing speed
needle valve regulates fluid pressure into the main valve cover
chamber, controlling the valve closing speed.
If the downstream pressure fluctuates slightly above the desired
set point, turn the adjustment screw OUT, counterclockwise,
increasing the rate of closing.
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 valve opening is too slow, turn the adjustment screw OUT,
counterclockwise, increasing the rate of opening (See Figure 4B).
If valve opening is too quick, turn the adjustment screw IN, clock-
wise, decreasing the rate of opening (See Figure 4A).
