CSA ARGO 3F 1" Combination Air Release Valve PN16 with Threaded Outlet

Controlled air discharge
During the pipe filling it is necessary to discharge air as water flows in. The air valve ARGO 3F, thanks to the aerodynamic full port body and float, will make sure to avoid premature closures of the mobile block during this phase.

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.
