Air Valves
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
costs.
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.
Val-Matic has developed the most comprehensive line
of air valves available today. From simple lever Air
Valves to Air/Vacuum Valves to 20" custom Combination
Valves, all are provided with stainless steel trim
and floats as standard. All Val-Matic Air Valve floats
are unconditionally guaranteed. Two papers on air
valves, as well as a sizing calculator are available
on request. |
