Single Ball Air Release Valve for Water Line
Features
Our high-quality ductile iron flange air valves comply with industry standards, and the seals and hot melt epoxy resin that come into contact with water are certified for drinking water. As a key component in water pipe systems, air valves help to release air from pipes or suck in air during drainage to prevent vacuum formation. The air valve ensures smooth flow of the medium, reduces energy loss, and protects the safety of pipelines and systems.
The installation location of air release valves depends on specific standards and is usually installed near long pipelines, high points, pump stations, and control valves. Because these locations are prone to air accumulation.
Mainly used in drinking water, wastewater and other water systems, such as:
● municipal water supply,
● sewage treatment plants,
● irrigation and agriculture,
● industrial fluid transportation
