Product Description

Product Description

Air Release Valves function to release air pockets that collect at each high point of a fully pressured pipeline. Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.

Automatic Air release Valve
Typically used in applications where air builds up in pipelines creating unwanted stresses and hammer
Also used to allow rapid charging or draining of pipelines
Normally positioned on an elevated section of pipeline
Especially suited for use on filtration systems, transmission pipelines and sewerage lines
Often used on irrigation systems
Combines air release with vacuum relief, suited for instant and continuous operation
Removable dirt cover
Low density ball within large air chamber
