STEP 5

Fine-tune the Pressure Reducing Control adjustment to the pressure

set point by turning the adjustment screw IN, clockwise to increase or

OUT, counterclockwise to decrease downstream pressure (See Image

7).

STEP 6

Opening Speed Flow Control Adjustment: The Opening speed flow con-

trol 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 down-

stream 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 Image 8).

Step 7

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.

Note: Check feature automatically functions with no adjustment required.
