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.
A fluid actuated, remotely controlled shut-off valve comprising: a valve housing including an inlet port and an outlet port whereby a controlled fluid is passed through the valve housing; an axial bore formed within the valve housing, the bore including a valve seat between the inlet port and the outlet port; a valve member slidable within the axial bore, the valve member being formed with a hemispherical poppet; the valve member having first and second positions whereby in the first position the hemispherical poppet is seated on the valve seat closing t...
