Abstract
A water valve having a housing defining an inlet and an outlet and a flow path extending therethrough, a pressure sensor configured to sense a water pressure at the inlet, a valve member situated within the flow path to open and close the flow path, a solenoid actuator, and a controller coupled to the pressure sensor to read the water pressure at the inlet and coupled to the solenoid to open and close the valve is provided. The controller determines an amount of time to hold the valve open in order to dispense an amount of water based on the water pressure. The controller commands the solenoid to open and close the valve to dispense the amount of water regardless of the water pressure. The controller is also configured to open the valve to reduce inlet pressure and prevent failure thereof.
