Abstract: Systems for isolating a region of a water distribution network are disclosed. In embodiments the systems and methods utilize at least one control valve system that includes a valve, a pressure sensor, an actuator, and a controller. The controller determines a water pressure at the control valve system based at least in part on a sensor signal from the pressure sensor. When the detected pressure is less than or equal to a low pressure threshold the controller issued a control signal that causes the actuator to move the valve to a fully closed position. Multiple control valve systems may be employed to isolate a region of a water distribution network. Methods of isolating a portion of a water distribution network, water distribution network including a control valve system, and control valve systems for use in water distribution networks are also disclosed.
