SCS-AS Raw water anti-slam surge prevention combination air valve for industry and aggressive environments


  • Very light weight
  • Low pressure sealing at 0.9m
  • Full 316 stainless steel construction
  • High reliable anti-slam function
  • Designed for Pressure Sewer Systems


The CSA Mod. SCS-AS is a compact, 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 release of air pockets from pressurized pipelines, and admits large volumes of air in the event of pipe draining or 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. As a result, it is a proven and reliable solution for aggressive environments such as seawater, coal seam gas extraction , process plants, refineries, and many more.
