About this product

The anti-surge triple function air release valve can be used for the following three applications:

Entrance of large volumes of air

During pipeline draining, or pipe bursts, it is necessary to bring in as much air as the quantity of out-flowing water to avoid negative pressure and serious damages of the pipeline, and to the entire system.

Controlled air discharge

During the pipe filling it is necessary to avoid rapid closures, responsible of water hammer effects. The anti-shock feature, will control the air outflow thus reducing the velocity of the approaching water column. The risk of over-pressure will therefore be minimized.

Air release during working conditions

During operation the air produced by the pipeline is accumulated in the upper part of the air valve. Little by little it is compressed and the pressure arrives to water pressure, therefore its volume increases pushing the water level downwards allowing the air release through the nozzle.

Key features

Body in ductile cast iron, PN40 bar rated, provided with internal ribs for consistent and accurate guiding of the mobile block

Drainage valve for chamber control and pressure relief during maintenance

Mobile block composed of a cylindrical float and upper disk in solid polypropylene, joined together by the air release system in AISI 316

Nozzle and gasket holder entirely made in AISI 316 and designed with gasket compression control to prevent aging process and consequent leakage during working conditions

Anti water hammer system (also called AS function), never in contact with water, obtained by a spring and shaft in stainless steel, disk with adjustable sonic nozzles for air flow control

Threaded outlet elbow to avoid spray effect, conveying spurts coming from the closure away from the valve. This feature will also allow the proper operation in case of flood, without the risk of contaminated water entering the pipeline

The air valve is fitted with a Y strainer to prevent debris, solids from reaching the upper part where the air release system and seat is located causing possible malfunctioning
