The CSA Mod. SCF -C is a compact, high-quality single chamber double function combination air valve.  The valve evacuates air during pipeline filling, allows the 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.  Entirely made in ductile cast iron, with air release system and seat in stainless steel, SCF-C is designed to ensure long lasting and reliable performance. It is also applicable in presence of raw sewage, keeping the solids and dirt away from the air release and sealing system.
