Abstract
Cryogenic valves with modular extended stems are disclosed. A modular stem assembly includes a stem including a first end and a second end. The modular stem assembly includes a first disk connector coupled to the first end of the stem. The first disk connector defines a slot configured to securely receive a stem head of a second stem assembly of the cryogenic valve. The first disk connector has a first outer radial surface to slidably engage an inner surface of a bonnet of the cryogenic valve. The modular stem assembly includes a second disk connector coupled to the second end of the stem. The second disk connector includes a head configured to be securely received by a stem slot of a third stem assembly of the cryogenic valve. The second disk connector has a second outer radial surface to slidably engage the inner surface of the bonnet.
