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. Val-Matic Clean Water Air Valves are certified to NSF/ANSI Standard 61 for drinking water components. All air valves meet AWWA C512 requirements. Two papers on air valves, as well as our sizing software are available on request or click here.
