Abstract
A valve assembly includes a housing having an inlet and an outlet spaced from each other, a first chamber defining the inlet, a second chamber defining the outlet, and a valve seat disposed between the first and second chambers, wherein fluid communicates between the first and second chambers. A valve head is disposed in the housing and moveable relative to the housing between an open position spaced from the valve seat and a closed position engaged with the valve seat. A valve stem is coupled to the valve head for moving the valve head between the open and closed positions. The valve stem is coupled to the valve head and rotatably and reciprocally movable for moving the valve head between the open and closed positions. A retainer plate is coupled to the valve head and a valve seal is disposed between the valve head and the retainer plate. The valve head includes an integrally formed rivet that secures the retainer plate to the valve head, thereby retaining the valve seal to the valve head.
