  • Patent number: 6363549
    Abstract: A valve system in which a magnetic valve is in series with a manually-operated valve and contact with the handle of the manually-operated valve initiates flow via the electronic controller whereas, upon loss of contact, a proximity detector controls the magnetic valve when an object, such as a user's hand, is in range. The manual contact is superordinate and proximity detection is subordinate and the proximity detector remains permanently switched on during the operating duration.
