Abstract:
A valve apparatus for controlling fluid flow between a fluid passage and a fluid delivery conduit therein includes a valve housing having first and second housing ports spaced therealong, and a driven member driveable toward and away from the first housing port. A closure member having a port is coupled to the driven member and slidable therealong. The driven member and closure member close and open the closure member port during movement of the driven member toward and away from the first port to induce and relieve a pressure differential, exerted on the closure member by fluid entering the housing, acting to slide the closure member along the driven member to close the first housing port. An inductive coil extends about an open end of the housing to receive a coil-equipped end of a probe therein to communicate the probe with monitoring and control systems across the valve.
