• Body and cover in ductile cast iron GJS 450-10 • Anti-surge system in stainless steel with adjustable air outflow nozzles • Air release system in stainless steel • Floats in stainless steel AISI 316 • Seat in stainless steel • Painting with fluidized bed technology RAL 5005
The CSA Mod. SCF-AS, is a high-quality single chamber tripple function combination air valve, with a built-in anti-water hammer non-slam surge prevention system.
The air valve allows the release of air pockets from pressurized pipelines, and admits large volumes 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 associated risk of water hammer.
Entirely made in ductile cast iron, with air release system and seat in stainless steel, SCF-AS is designed to ensure long lasting and reliable performance. It is also applicable in presence of raw sewage, keeping solids and dirt away from the air release and sealing system.
