3.0 - OPERATION PRINCIPLE
3.1 ARES N REGULATOR – BASIC INSTALLATION
The pressure regulator series ARES N works by principle of direct spring action against sensor element of outlet
pressure (diaphragm). The consumption variation and consequently change of pressure in the sensor element
(diaphragm) will change diaphragm position and diaphragm lever that acts the shutter shaft, increasing or decreasing the
valve passage in order to keep the outlet pressure constant.
In case of flow absence, the consequently outlet pressure increase is transmitted to the diaphragm resulting in this
upward movement; it will change lever position and shaft that will decrease the gas passage.
With gas consumption the opposite will happen and will open the main valve.
