Anti-slam surge prevention combination air valve figure LYNX 3F - AS

The CSA Mod. Lynx 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 ductile cast iron, with air release system and seat in stainless steel, Lynx 3F-AS stands out for its long lasting performances and reliability.
