Air Release Valve Automatic Stainless Steel Float Air Vent Valve for Water Pipeline

Air Release Valve

Air release valve is an essential accessory for water pipeline systems, used to automatically exhaust air generated during water transportation. When air accumulates inside the pipeline, the internal buoyancy mechanism will automatically open the vent to discharge air, and close tightly once the pipeline is full of water to avoid water leakage.

This valve effectively solves pipeline air blockage, reduces water flow resistance, avoids water hammer damage, and ensures stable and efficient operation of the entire water supply system. Adopting premium cast iron / stainless steel material, the product is anti-corrosion, wear-resistant and pressure-resistant, suitable for long-term industrial and municipal pipeline operation.

Available in multiple specifications from DN15 to DN50, the air vent valve supports custom pressure grades and connection methods. It is widely applied in water treatment projects, HVAC systems, fire protection pipelines, municipal water supply and industrial fluid conveying systems.
