TEMPER PROOF AIR VALVE FLANGED END
“aline” Make Tamper Proof Air Valve – Flanged End is specially designed for the automatic release and intake of air in pressurized water pipelines while preventing unauthorized adjustment or tampering. The tamper-proof design ensures reliable operation, protects the valve settings, and minimizes maintenance, making it ideal for municipal water supply, irrigation, and industrial pipeline systems.
The valve automatically releases trapped air during pipeline filling and operation while allowing air to enter during pipeline draining or vacuum conditions, preventing vacuum formation, water hammer, and pipeline damage. Its flanged end connection provides secure installation, excellent sealing, and long-term durability under demanding operating conditions.
Manufactured from premium-quality materials with precision engineering, the ALINE Tamper Proof Air Valve offers corrosion resistance, dependable performance, and a long service life. It is widely used in Water Distribution Networks, Irrigation Projects, Water Treatment Plants, Pumping Stations, Fire Fighting Systems, Industrial Utilities, and Infrastructure Projects where efficient air management is essential.
Designed for maintenance-free operation and superior reliability, the ALINE Tamper Proof Air Valve ensures smooth pipeline performance, improved system efficiency, and reduced operational costs.
