Abstract: The self-charging programmable water valve provides programmed watering control to a portion of an irrigation zone. A rechargeable battery provides electrical power to control the valve, which includes a pulse charger activated by water flow through the valve for recharging the battery. A pressure sensor is connected to a control circuit that activates the water valve when water pressure detected by the sensor exceeds a predetermined limit. A first digital timer determines valve open duration, and thus how long the portion of the zone will receive water. A second digital timer begins a count cycle after the first digital timer shuts down the water flow to the connected branch. The second digital timer is provided to prevent false reactivation of the water valve during a zone watering cycle, thereby preventing excessive watering of the portion of the zone controlled by the programmable water valve.
