ABSTRACT:
An improved pilot operated valve which may be used in fluid control systems which may have one or more latching unit for controlling the valves. The valves utilizing a concentric arrangement of the major components thereof, each being coaxially located with respect to a single housing member. These major components include the valve closure member, the pilot valve, the diaphragm separating the high and low pressure areas, and the latching actuator controlling the pilot valve. A mounting flange member is provided for threading into a valve body, and is in turn threaded to the valve body member so that the entire valve assembly may be rotated much like a conventional valve handle to provide a flow control, and a manual shutoff if desired. The control electronics may be battery operated and may locate with respect to one valve to provide drive signals to control one or more valves in sequence. Other controls and actuators may be used.
