A shut-off valve may control the flow of high-pressure fluid in an on or off manner. The valve includes a valve housing having an axial bore therethrough with a valve member slidable therein. The valve member is formed with a hemispherical poppet which, in one position, is seated between a valve inlet port and a valve outlet port. The valve member is floatably mounted within the axial bore so as to render the hemispherical poppet self-aligning with respect to the valve seat. The valve is remotely actuated by a valve actuating fluid. |
