Description
The FOX 3F C Mod. is a high-performance full bore, single chamber combination automatic air valve. It allows the release of air pockets accumulated in pressurized pipelines during operation and admits large volumes of air in case of pipe draining or bursts, preventing vacuum and negative pressure conditions.
The conveyed outlet version is equipped with a cover with threaded outlet for connection to an external pipe, allowing safe and controlled air discharge. This configuration prevents insect ingress and is suitable for submerged installations.
Entirely made in ductile cast iron, with air release system and sealing seat in stainless steel, the FOX 3F C guarantees reliability, operational precision and long service life.
