Air Release Wastewater Valves

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.

Benefits and features

Wastewater Air Valves perform two important functions in a piping system: they maintain system design effi ciency and provide system protection. Exhausting and admitting air keeps the system from restricted fl ow reducing pumping costs and reduces the potential for destructive surges and water hammer that can collapse a pipeline.
