Abstract:
An electrically operable valve assembly for controlling a household water supply, said valve assembly comprising:a water supply inlet; a water supply outlet; a pressure regulator for reducing a water pressure level of said water supply inlet; a piston disposed between said water supply inlet and said water supply outlet for controlling a flow of said household water supply, wherein said piston is opened by a pressure drop introduced in the flow of said water supply; a bypass channel extending between said water supply inlet and said water supply outlet for reducing said pressure drop, whereby said piston is allowed to close; an electrically operable valve element for controlling a flow of said household water supply by interrupting flow through said bypass channel; a housing for containing said pressure regulator, said piston, said bypass channel and said electrically operable valve element, whereby said electrically operable valve assembly valve assembly comprises an integral assembly attachable between a water supply via said water supply inlet and a household water system via said household water supply outlet; and a ball disposed within said bypass channel, and wherein said bypass channel defines a chamber having a diameter larger than a diameter of said ball wherein said ball may move and an inlet having a diameter smaller than said diameter of said ball whereby said ball may seat against said inlet, blocking a reverse flow through said bypass channel from said water supply outlet to said water supply inlet.
