Air/Vaccum Release Valves – Automatic Air Release Valves

Air Valves – Air Relief Valves

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.

Vacuum Priming

The purpose of a Vacuum Priming Valve is to automatically allow air to be drawn out of the pumping system until the pump fills
