DOUBLE AIR VALVE FLANGED END

“aline” Make Double Air Valve – Flanged End is designed to automatically release trapped air from pressurized pipelines and admit large volumes of air during pipeline draining or vacuum conditions. Combining the functions of an Air Release Valve and an Air & Vacuum Valve, it ensures smooth pipeline operation, prevents air lock formation, reduces water hammer, and protects pipelines from vacuum damage.

The flanged end design provides secure, leak-proof installation and excellent mechanical strength for long-term industrial and municipal service. Manufactured from premium-grade materials with precision engineering, the valve delivers reliable performance, corrosion resistance, and minimal maintenance even in demanding operating environments.

ALINE Double Air Valves are widely used in Water Supply Systems, Irrigation Networks, Water Treatment Plants, Pumping Stations, Fire Fighting Systems, Sewage Lines, Industrial Pipelines, Cooling Water Systems, and Infrastructure Projects where efficient air management is critical for system performance and equipment protection.

Designed for dependable automatic operation, the ALINE Double Air Valve improves pipeline efficiency, extends equipment life, and reduces maintenance costs.
