SCS-AS
Raw water anti-slam surge prevention combination air valve for industry and aggressive environments
|
The CSA Mod. SCS-AS is a compact 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 stainless steel, its design allows for the presence of solids and raw water without any risk of clogging and malfunctioning making it a well proven and reliable solution for aggressive environments like seawater, process plants, refineries and many more.
