CSA ARGO 3F AS 1" Anti-Surge Combination Air Release Valve PN16

Controlled air discharge
During the air discharge it is necessary to avoid rapid closures of the float, responsible of water hammer effects. The anti-shock device will control the air outflow reducing the velocity of the approaching water column and minimizing the risk of overpressure.

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 automatic opening.

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 outflowing water to avoid negative pressure and serious damages to the pipeline, and to the entire system.
