Cryogenic cylinder control system, globe valve, and solenoid valve

A valve for conveying fluid, comprising:

• a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
• a gland nut mounted to the valve body;
• a lower spindle threadably engaged to the valve body;
• a seat disc mounted to the lower spindle;
• an upper spindle matingly engaged to the lower spindle such that rotation of the upper spindle causes the lower spindle to rotate;
• and
• a biasing member extending between the upper and lower spindles and biasing the upper spindle into sealing engagement with the gland nut, wherein the valve is movable between a closed configuration in which the seat disc sealingly engages the valve seat and prevents fluid flow from the inlet to the outlet and an open configuration in which the seat disc is disengaged from the valve seat and enables fluid flow from the inlet to the outlet.

A manual valve module for a cryogenic cylinder control system comprising:

• a housing;
• and
• a manual valve supported by the housing, the manual valve comprising:
• a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
• a gland nut mounted to the valve body, the gland nut including a sealing cavity defined by a plurality of inner surfaces;
• a lower spindle threadably engaged to a lower portion of the valve body, the lower spindle including a sealing portion configured to engage with the valve seat;
• an upper spindle disposed in an upper portion of the valve body, the upper spindle engaged to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle;
• a sealing member disposed around a portion of the upper spindle;
• and
• a biasing member extending between and exerting a biasing force on the upper spindle and the lower spindle, wherein the biasing force exerted on the upper spindle causes the sealing member to sealingly engage with the sealing cavity of the gland nut.

A manual valve module for a cryogenic cylinder control system, comprising:

• a housing;
• and
• a manual valve supported by the housing, the manual valve comprising:
• a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
• a lower spindle threadably engaged to a lower portion of the valve body, the lower spindle including a sealing portion configured to engage with the valve seat;
• an upper spindle disposed in an upper portion of the valve body, the upper spindle engaged to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle;
• and
• a biasing member extending between the upper spindle and the lower spindle, wherein rotation of the manual valve in a first direction causes the upper and lower spindles to rotate relative to the valve body.
