Cryogenic valves are disclosed. A valve for includes a valve body, a valve seat, a gland nut coupled to the valve body, and a lower spindle threadably engaged to the valve body. The lower spindle defines a first bore. The valve includes a seat disc mounted to the lower spindle and configured to engage the valve seat in a closed configuration and be disengaged from the valve seat in an open configuration. The valve includes an upper spindle defining a spring bore. A portion of the upper spindle is received in the first bore to matingly engage the upper spindle to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle. The valve includes a spring that is at least partially disposed in the spring bore of the upper spindle and is configured to bias the upper spindle to sealingly engage the gland nut.
