Triple function automatic combination air valve with ducted outlet fig. FOX 3F C

The Mod. FOX 3F C automatic combination air valve is a full bore, single chamber, high performance air valve. It allows air pockets accumulated in pressurised pipes to be vented during service and large volumes of air to be admitted in the event of draining or a pipe burst, preventing the formation of vacuum and negative pressures.

The ducted outlet version has a cover with a threaded outlet for connecting an external pipe, allowing safe, controlled air discharge. This configuration prevents insects from entering and is suitable for submerged installations.

Made entirely of ductile iron, with a stainless steel venting system and sealing seat, the FOX 3F C guarantees reliability, accurate operation and long service life.
