Ductile iron body, flanged connection according to EN 1092-2. Float part made of polyethylene which can be replaced easily.
If the air is not discharged in water transmission and water network when on duty, air is collected in certain areas and may cause the danger of stopping the waterflow. This danger is increased with the congestion, and causing the pipeline to explode and major damages.
Single Orifice ARV is installed on the pipe with a flange, releases the air recevied from its flange connnection through the orifice located above the float part. When the air release is completed, the float travels upside with the water force and closes the orifice outlet, thus preventing the leakage of water.
The biggest problem of Single Orifice ARV’ is the ARV blockage. For this reason, ARV’s on the line must be checked at certain intervals.
While the pipeline is taken into service, it enables the air accumulation and discharges out of the system.
With the discharge of air inside the system, the fluid will reach the release level; so the float ball valve inside the body elevates on the water and places on the sealing seat and turns to closed position.
When it is needed to discharge the filled pipelines, it is required to fill air in place of the fluid leaves the system.
Body and cover of ductile iron with blue epoxy coating
Release valves can be manufactured with flanged or screwed ends.
