Airvent

The 9702 is an automatic air release valve designed to purge trapped air pockets from wet fire sprinkler systems while sealing tight against escaping water. Rated for 200 psi working pressure, it is built with an ASTM A536 ductile iron body and cover, an AISI 304 stainless steel float and leverage linkage, and a Viton orifice sealing button. Offered in ½", ¾", and 1" NPT or BSPT female threaded connections with FM Approval, it protects fire piping from air-induced surges and internal corrosion.
