PReSSuRe RegulAToR AdjuSTMenT
the variable setting pressure regulator has been calibrated from the factory and set to a specific regulation setting.
this setting will not normally need to be changed. the variable pressure regulator has a pointer and a pressure
indicating scale on the side of its body with a range of 60 psI to 120 psI. If pressure setting adjustments are required
it is important to note the following:
• The calibrated pressure setting from the factory is very accurate. However, the pressure indicating scale is
only a pressure setting reference when making adjustments in the field. For more precise pressure regulation
adjustment in the field, use a pitot gauge at the nozzle to the check pressure.
to raise the pressure setting on the variable setting regulator, turn the adjusting knob clockwise (fig 146). each full
turn clockwise of the adjusting knob will increase the pressure approximately 10 psI. use the scale on the side of the
regulator’s body to estimate pressure.
to lower the pressure setting on a variable setting regulator, turn the knob counter-clockwise (fig 146). to obtain
more accurate setting when reducing the pressure, it is highly recommended that the setting be taken down to
approximately 10 psI below the desired pressure setting and then turn the knob clockwise to the desire setting.
