3.3 PILOTS
The pressure regulator model ARGOS manufacture by GASCAT use pilot model G80, G30F or G32F depending of the
desired set-point.
This pilot is responsible by the control of feed pressure of main regulator actuator and by consequence of the pressure
regulator aperture.
The set pressure of the G80 pre pilot It should be 0.8 bar more than the desired outlet pressure, for example if you
want to adjust the valve in 0.5 bar, you must adjust your pre pilot in 1.3 bar. You can verify the pre pilot adjusted pressure
in the pressure gauge connected to the pre pilot.
3.4 FILTERS
The GASCAT pilot blocks, consisting of a pilot and pre-regulator always have a mechanical barrier against solid
impurities; this barrier comprises a polypropylene filter element of 10-micra filtration grade.
This barrier is intended to prevent that solid contaminants contained within the pipework can clog or damage the
internal parts of pre-regulator and of the pilot. However, it is important to note that this filter does not replace the
filtration system that shall be provided in preliminary steps to pressure regulating to leave the fluid clean and
according to correct operating conditions. 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.
