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. - Page 8 Installation, Operation and Maintenance Manual MI–42 Pressure Regulating Valve – Model Ares N ARES N Prepared by Verified by/ Approved by Date Revision Page José Junior Vanízio Lizo Jamerson 24/03/17 8 of 21...
