GOLIA 3F-RFP
The CSA Mod. GOLIA 3F-RFP, is a full bore high quality single chamber double function combination air valve with a built in anti-water hammer non slam surge prevention system. The air valve allows release of air pockets from pressurized pipelines, and admits large volume of air in the event of pipe draining/burst, to prevent vacuum and negative pressure conditions. During outflow the air valves senses the increase in air velocity and differential pressure using, if required by excessive values, the RFP (anti-surge) flat to 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 in special alloys like stainless steel, Duplex or Super Duplex, GOLIA 3F-RFP is a well proven and reliable solution for aggressive environments like seawater, process plants, refineries and many more.

GOLIA 3F-AS
The CSA Mod. GOLIA 3F-AS, is a high quality single chamber double function combination air valve with a built in anti-water hammer non slam surge prevention system. The air valve allows release of air pockets from pressurized pipelines, and admits large volume 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 in special alloys like stainless steel, Duplex or Super Duplex, GOLIA 3F-AS is a well proven and reliable solution for aggressive environments like seawater, process plants, refineries and many more.
