Air Release Assemblies (ARA)
Air Release Assemblies are highly reliable and easy to maintain. They can be quickly converted to automatic air/vacuum operation without the need to replace piping by using an ARV21 or ARV40 valve. This allows greater system flexibility because systems can be designed to use ARA Assemblies with manual valves, and more costly automatic valves can be installed later in locations where they are necessary. The valves and pressure gauge port can be isolated for the installation or removal of components.
