Ø Specifications 

Ø Operation

To increase pressure, turn the regulator adjustment knob in a clockwise direction. To decrease pressure, turn the adjustment knob in a counterclockwise direction.

Principle of Operation

(Refer to Figure 1)

The range spring, which has been compressed by the adjustment knob and screw, causes the pintle valve to move downward, allowing air to flow. The pressure builds up against the diaphragm until the pintle valve throttles. This is the set pressure which is closely maintained in the following manner: A drop in the regulated line pressure will cause a decrease in the pressure against the bottom of the diaphragm. The range spring forces the diaphragm down against the reduced pressure causing the pintle valve to open, admitting more supply air, until the pressure below the diaphragm balances the spring force. Diaphragm upward motion causes the exhaust valve in the diaphragm to open. The excess pressure rises into the spring cavity through the exhaust valve and vents to atmosphere via the exhaust vent.
