Most regulators use spiral springs as the loading device. It is important to reduce the load of these springs relieving
their loaders as much as possible. In some cases, some residual load may last, even though the spring is relaxed to the
limits of its housing.
There is not a recommendation about the frequency to change the repair kit due several different variables in the
process that changes installation by installation as, for example, process gas quality, service conditions etc. The repair kit
should be changed when the regulator has problems during operation, as leakage, increase in set pressure and also
others that become the quality and regulator performance different.
However, Gascat recommends that after all regulators opening during maintenance service the repair kit must be
changed. It is also indicated to change a complete repair kit and not only specific part (example o’ring, obturator), to have
the all spare parts with same life time.
Gascat already inform to avoid all non original and genuine parts.
2 – INTRODUCTION
2.1 – SCOPE OF MANUAL
This Instruction manual has as objective supply information about operation, installation and maintenance about
ARGOS WA pressure regulator manufactured by GASCAT.
2.2 – DESCRIPTION
Argos Axial WA Series is a regulator designed by Gascat’s engineering, that is included into the pilot-operated pressure
regulators family, to be applied with all gases.
This wafer type regulator is developed with face-to-face short what allow an utilization with pressure regulating stations
with few available space for installation; it is also for compact installations with underground stations, saving space and
reducing the costs with boxes and skids.
Because of robust construction, simple, flangeless type, with few components, it also reduce non-programable
maintenance. These qualities result in a repair kit with low price. Additionally, this valve can be supplied with pipe screws
necessary to assemblage in the pipe or skid (it is not included in the standard version – it should be requested).
Easy installation and simple regulation; the restrictor installed near the inlet pilot according to the schemes below
adjusts the loading and unloading pilot velocity allowing the adjustment of this relative response to the set-point achieved
and lock-up pressure.
