An electrically operable valve assembly having an integral pressure regulator provides ease of installation and compact packaging for a water supply control system. The valve assembly is particularly useful for systems that control household water supplies to prevent flooding, but is also useful in other applications such as agricultural and industrial systems where water pressure determined water flow volume must be predicted accurately. The valve may also incorporate a flow meter having a positive flow characteristic permitting determination of very low flow rate flow and the valve may incorporate a manual control. All of the controls and features are integrable within a compact package that occupies essentially the same volume and piping space as a conventional electrically operable valve.
