Abstract: Realized is a sealing member which exhibits excellent sealing properties even at a low temperature and a high pressure. A sealing member (100) includes: a first pressing part (110) that presses a first side part of a gap by pressing from a lateral direction; a second pressing part (120) that is pressed against a second side part of the gap by the pressing from the lateral direction; and a part (122) that induces deformation of the sealing member (100) such that the sealing member (100) is strained toward the second side part by the pressing from the lateral direction.

Abstract: A valve (10) of an embodiment of the present invention has a tapered section (55) on an opening side of a depression (51a) of a body (1). When a projection (4b) of a ball (4) is inserted into the depression (51a), a part of a tip end edge of the projection (4b) is brought into contact with the tapered section (55), and the tapered section (55) guides the projection (4b) so that the entire circumference of the tip end edge of the projection (4b) is located on a bottom side with respect to the tapered section (55).

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.
