Air & Vacuum Release Valves – Elite Flow Control UK Limited

Air Release Valves, sometimes referred to as “small orifice valves,” are often fitted at the highest point on a pipeline to continually release unwanted air during system operation to protect against unwanted surges and maintain system efficiency.

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 hammers normally associated with uncontrolled air or a vacuum condition within the piping system.

Air/Vacuum Release Valves / Combination Air Valves

Air/Vacuum Release Valves also called Combination Air Valves, often referred to as “large orifice valves”, are used to allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained. When draining the pipeline, the float drops, allowing air to enter, preventing loss of pressure, possible pipeline collapse, and damaging water column separation and maintaining system efficiency and preventing pipeline surges.
