Page 10: Operation 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 11: Regulator - Active / Monitor System
Installation and Operation Manual MI-23 Argos - Pressure Regulating Valve 3.2 REGULATOR - ACTIVE / MONITOR SYSTEM In the active / monitor system, the regulator working principle is similar then previously explained. 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. -
Page 12: Pilots
This filter is designed to serve as the last barrier to solid contaminants. The ARGOS pressure regulators can be provided with an F-10 filter mounted in separate from the pilot unit, or in a compact version, with the filter element already coupled to the pre-regulator. -

Page 15: Installation
Do not install insulating valves in the sensing line of pressure regulators. The pressure regulator model Argos needs only one connection to the process per valve, that is the sensing line of pilot, independently of system configuration (active / monitor, working monitor and only active regulator). Exception only for flow limiter that have two extra connections in the orifice plate. -

Then, it Gascat recommends to check the using external pneumatic source connected directly in the actuator, before proceeding the stream pressurization. The regulator model Argos is not supplied adjusted. It tends to preserve the life time of internal parts. So that it is necessary to adjust the regulator prior to operation. -
Page 21: Stand By Line Adjustment
4.6.3 STAND BY LINE ADJUSTMENT When the pressure regulator is installed in a stand by line Gascat recommends to realize the same procedure of item 4.6.2, however the regulator set point shall be 15%~20% less than the regulator set point of working line. -

Installation and Operation Manual MI-23 Argos - Pressure Regulating Valve 5) As there is no pressure downstream the regulator the slam shut valve GIPS-FC will be closed. So that press the by-pass or push button in the slam shut valve to pressurize the line between the slam shut valve and the pressure regulator. -

(impurities), natural wear, and fault during the equipment operation. It is important to keep in mind that the operation and maintenance of GASCAT equipment should only be performed by highly skilled and trained personnel, preferably by teams trained by GASCAT’s instructors. -
Page 26: Maintenance
Before starting maintenance of GASCAT’s pressure regulators, you shall always assure yourself to have a replacement kit with original GASCAT parts, as well as this instruction manual for reference of how to work safely and efficiently during the equipment maintenance. -
