Abstract:
To provide a face-to-face expandable valve that can be adjusted between predetermined faces with high accuracy by rotating one part at each fastening point, can be connected so as to prevent occurrence of rust in a state where a connection side with an external pipe is moved even after adjusting between the faces to ensure high sealability, and has high versatility without requiring complicated processing.SOLUTION: A movable side flange 3 is provided on a fixed flange 10 of a valve box 2 so as to be able to move forward and backward, to expand and contract a gap W between faces. A cylindrical expandable nut 5 screwed into a long bolt 4 fixed to the movable side flange 3 is inserted into the fixed flange 10, and the expandable nut 5 is rotated to expand and contract the movable side flange 3 with respect to the fixed flange 10.SELECTED DRAWING: Figure 2
