Description
The Metraflex MVC150050 (Model MVC-15) is a cast iron automatic air vent engineered for reliable air elimination in hydronic heating and cooling systems. Featuring a 1/2″ Female NPT connection and a precision 1/16″ orifice, this vent continuously and automatically purges trapped air from piping systems — protecting pumps, coils, and heat exchangers from air-induced efficiency loss and noise.
