It is two critical time in the operation of a pipeline.
During filling, air that occupies the empty pipe must be evacuated
ahead of the incoming liquid in a controlled and efficient
manner so that surge and water hammer are minimized and liquid
completely fills the pipe. During draining, whether planned
or unexpected, air must be admitted into the system to replace
the out flowing liquid to avoid excessive vacuum and possible
pipeline damage.
Air release valve are designed to release accumulated air
pockets from the system, while pressured pipelines. Air pockets
increase energy consumption because pumping operation will
be at higher water heads to overcome pressured air.
Air release valves are have function to protect high shock
and surge pressure, water hammer and liquid overflow from
fresh or sea water pipelines.
PROSAVE's valve can provide low cast insurance to protect
expensive maintenance cost of pipelines and pump systems.
