ABSTRACT:
A flow control valve is provided, especially for controlling the flow of water heated to near its boiling point. In order to limit cavitation and improve sealing characteristics of the valve, the valve seat is formed as an integral part of a plastic valve housing, on a thin inwardly protruding plate. The closure element or sealing body is formed of an elastomeric material stretched over a support plate, in turn attached to a movable plunger of, for example, an electromagnetic operated valve plunger. The closure element is formed as a tapered conical member which engages, with its tapered peripheral surface against the seating plate. Preferred embodiments of the invention relate to valve arrangements having an annular ventilating slit formed to open immediately downstream of the throttling point of the valve.
