The CSA Mod. GOLIA 3F-AS, is a high-quality single chamber triple function combination air valve with a built-in anti-water hammer non-slam surge prevention system. The air valve allows the release of air pockets from pressurized pipelines and admits large volumes of air in the event of pipe draining/burst, to prevent vacuum and negative pressure conditions.
The anti-shock mechanism, with adjustable nozzles, will control the air outflow rate thus avoiding fast approaches of water column with potential sudden closures of the mobile block and the risk of water hammer. Entirely made of special alloys like stainless steel, Duplex or Super Duplex, GOLIA 3F-AS is a well proven and reliable solution for aggressive environments such as seawater, process plants, refineries, and more.
