An electrically-operated control valve includes a rotor rotatably mounted to a first position connecting a fluid inlet port to a fluid outlet port, or a second position disconnecting the fluid inlet port from the fluid outlet port; a battery-operated electrical rotary motor for rotating the rotor; and limit switches for deenergizing the electrical motor when the rotor arrives in either the first or second positions. The electrical motor is coupled to the rotor by a speed-reducing, torque-increasing transmission such that very little electrical power is r...
A water distribution system, comprising: a water distribution conduit; a distribution valve within said water distribution conduit for controlling the distribution of water therethrough; and an electrically-operated control valve serving as a pilot valve for controlling said distribution valve; said control valve comprising: a valve housing having a fluid inlet port a control port, and a venting port; a rotor formed with a passageway therethrough rotatably mounted within said housing to a first position connecting said control port to said inlet port via...
