Standard Gauges – Calibration Guide Cont.
STEP 1
Turn the Black regulator counter clockwise all the way out as shown. (B)
Open the valve on the nitrogen bottle (A). The inlet gauge should indicate the pressure in the Nitrogen bottle.
Verify it is over 1,000 PSI.
STEP 2
Tighten the BLUE regulator fully by turning clockwise, as shown. Be sure not to over- tighten. (C)
Review chart on page 15 to find the “Line set pressure,” which is the pressure you want the valve to OPEN in
case of an over pressure event. To the right of that is the required Nitrogen pressure for the valve. Field use
has shown, due to variables such as thermal compression and friction, the best practice is the turn the BLACK
(B) regulator knob clockwise until the Nitrogen line pressure reaches over 40 PSI over that desired pressure.
The operator will hone in on that set pressure in later steps.
