Abstract
Shut-off valves for cryogenic fluids are disclosed herein. A shut-off valve includes a body that defines void(s) in fluid communication with a valve inlet and a valve outlet. The shut-off valve includes a valve seat defined by the body, a housing connected to the body, and a valve spindle disposed within the housing. The valve spindle includes a seat disc configured to sealingly engage with the valve seat. The shut-off valve includes a buffer composed of a cryogenic temperature resistant material circumferentially surrounding and connected to at least a portion of the valve spindle and slidingly engaged with an internal surface of the housing. The shut-off valve includes a valve actuating member operatively connected to the valve spindle and configured to cause an axial movement of the valve spindle, the seat disc, and the buffer to control a flow of a fluid.
