Page 9: Operating Principle
Installation and Operation Manual MI-44 Argos WA - Pressure Regulating Valve 3 – OPERATING PRINCIPLE 3.1 – THE REGULATOR The pressure regulator Argos works by principle of drop pressure in the upper chamber (diaphragm of main valve). In the flow absence the pressure regulator stays close, because the pressure in the upper chamber of diaphragm (feed by the pilot), added to the spring force is superior to the pressure that acts below the diaphragm (inlet pressure). - Page 10 Installation and Operation Manual MI-44 Argos WA - Pressure Regulating Valve The upstream regulator (monitor) keeps in the open position, because the pilot sensing line monitors the active pressure regulator set point and, as its set point is lightly higher, the pilot keeps opened. The reason that this pilot stays opened is due of pressure under its diaphragm that added to the obturator spring that are lower than the regulating spring force that moves this obturator set downward opening the pilot.

3.3 – PILOT The pressure regulator model ARGOS WA manufacture by GASCAT use pilot the G-30 or G-80 model depending of the desired set-point. If the set-point is greater than 0.7 bar, applies the G-30. This pilot is responsible by the control of feed pressure of main regulator actuator and by consequence of the pressure regulator aperture. -
