Beschreibung
Zusammenfassung:	A valve device includes a metal valve body defining a water passageway between an inlet and an outlet of the body. A valve seat of a different material than the valve body is insert-cast molded integral with the valve body. The configuration of the valve seat and the mass of the valve body surrounding the seat being sufficiently large reduces a chilling effect during molding such that a pressure-tight and waterproof interface is formed between adjacent surfaces of the valve body and the valve seat.
