A Air Maintenance Pressure Regulator, 1/4 in, 5 to 75 psi, Steel Body

The pressure regulator is factory set to maintain a nominal system air or nitrogen pressure of 23 psi (1.6 bar). In order to change the outlet pressure, loosen the locknut at the top of regulator and turn the adjustment screw clockwise to increase pressure. To decrease the pressure, turn the adjusting screw counter clockwise. The resulting pressure can be determined at the sprinkler system air gauge or the optional gauge location provided on the device, once the flow or air or nitrogen through the device has ceased.
