Abstract:
1. A system for the remote control of water flow through a water-supply line, comprising, a transmitter for sending coded stop and start radio frequency (RDF) signals, and a water shut-off unit, said water shut-off unit comprising: a housing that is substantially sealed to prevent the incursion of water or moisture, a motorized ball valve located within said housing and connected to said water supply line such that the water flows through said housing and said motorized ball valve, a controller located within said housing and capable of receiving the coded RF signals from said transmitter, said controller having means for deciphering said coded RF signals and means for sending an electrical signal corresponding to said decoded signal to said motorized ball valve; a power supply source for providing electrical power to said controller and said motorized ball valve, wherein, when said motorized ball valve is in an “open” position and said transmitter transmits a coded “stop” signal to said controller, said controller actuates said motorized ball valve to rotate 90° to a “closed” position and thus stop the flow of water and, conversely, when said motorized ball valve is in a “closed” position and said transmitter transmits a coded “on” signal to said controller, said controller actuates said motorized ball valve to rotate 90° to an “open” position and thus start the flow of water.
