Abstract
An air release valve (10) includes a housing (11) fluidly connectable to a water line, a valve seat (12) secured to a portion of the housing (11) and formed with one or more air exit passageways (14), a seal (18) formed as a spring disc and including a stem (28) slidingly engaged with the valve seat (12), and a weight (20) coupled to the seal (18). In a sealed configuration the seal (18) presses against the valve seat (12) and seals the one or more air exit passageways (14) from air passing therethrough and in an open configuration the seal (18) is moved by the weight (20) so that the seal (18) is not pressed against the valve seat (12) and allows passage of air through the one or more air exit passageways (14).
