ABSTRACT:
A device for distributing pressurized water to a plurality of sprinkler lines is provided. The valve and valve control portions are centralized, and thus no electrical connection to remote locations is required. The valve system is modular so as to permit addition or deletion of modules for adding or removing control of sprinkler lines. A stepper motor and cam shaft system permits expenditure of energy only during change-of-state events, so that no electrical energy need be consumed to maintain a watering state. A generator which produces electrical energy from the pressure head of a pressurized water source provides electrical energy for operating a motor and a motor controller, such as a device including a microprocessor.
