a closed position 22 a flow restricting position the valve 14 may be of the sliding variety such that the valve 14 will rotate into the closed position 22 a sliding type valve 14 lessens the force necessary to restrict the flow through the automatic water faucet 30 the valve 14 in the closed position 22 prevents water from flowing from a water supply 26 to the automatic water faucet 30 generally the flow rate through an automatic water faucet 30 is less than 2 gallons per minute however the present invention may also be used in higher flow rate environments such as roman tubs or bathtubs where flow rates may exceed 5 gallons per minute in addition flow rates through plumbing devices 12 may be controlled by mechanisms upstream or downstream from the valve 14 the spring 34 is in communication with the valve 14 when the valve 14 is in the closed position 22 the spring 34 maintains a more relaxed position 38 a power supply 54 powers a powered actuator 50 under normal operation the powered actuator 50 moves the valve 14 between the closed position 22 and an open position 18 a flow permitting position an object detection system 58 can trigger the valve 14 to move from the closed position 22 to the open position 18 when.
