MEDIUM PRESSURE REGULATOR | COMMISSIONING | REV. A
8.6.1 - PRESSURISING WITH EXTERNAL SOURCE
If the setting spring of the main regulator (1) does not reach a sufficient pressure to put into service the regulator with
in-line monitor function (2), you may pressurise the chamber (A) of the control head of the main regulator (1) by using an
external source.
Pressurisation can be done:
• with external lines;
• manually.
The introduced pressure is controlled by using pressure gauges or transducers.
To correctly discharge the introduced pressure, make sure there is an additional bleed cock (18).
