AIR VALVES:
Allowing pipelines to Breath

BLESSED, make Air Release Valves are made to deal with the regular and obvious operational difficulties of a pipe line; viz:
A] Release of low quantity Air, at the pipe line, when the line is active.
B] Release of very large volume of Air at a very high working pressure, at an early stage of water filling up of the empty pipe line and
C] Allow Air to get into the pipe line and helps the pipe line to maintain equal pressure inside it, compared to the outside atmospheric pressure and thus not let the empty pipe line to be crushed by the outer atmospheric pressure.
