perform two important functions in a piping system.
They maintain system design efficiency and provide
system protection. System efficiency is maintained by venting air via the air valves from
the system that can restrict flow and increase pumping
Protection is provided by exhausting and admitting
air through the air valves during system operations including start-up, shutdown,
and critical conditions such as power failures or
line breaks. The exhausting and admitting of air during
these conditions will reduce the potential for destructive
surges and water hammer normally associated with uncontrolled
air or a vacuum condition within the piping system.
