The CSA Mod. FOX 3F is a full-bore high-quality single chamber double function combination air valve that 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 of ductile cast iron, with air release system and seat in stainless steel, Fox 3F stands out for long-lasting performance and reliability.

Valves are manufactured to Australian requirements such as AS4020 , AS4158 , AS4087  and are tested in an fully accredited testing laboratory by SAI Global
