Abstract:
A cryogenic globe valve that prevents a high sealing property and safety from being lost even through a large number of times of opening and closing for a cryogenic fluid and is easily maintained, although it has a simple structure. The cryogenic globe valve has an axial cylindrical portion as a long-neck structure extended to its body, in which a resin-made valve disk having a conical surface having a reduced-diameter tapered shape is attached to a lower end of an elongated stem such that the resin-made valve disk is three-dimensionally operable with respect to the stem even under an extremely low-temperature condition.
