A split valve (100) includes: an upper valve body (12) having a spherical surface (12a) abutting on a seat surface (11a) of a discharge port (4) to block the discharge port (4) and a hollow (12b) on a lower surface; a lower valve body (32) that blocks a receiving port (5) by causing a spherical surface (32c) to abut on a seat surface (31a) of a receiving port (5) and has a protrusion (32a) fitted to the hollow (12b) of the upper valve body (12) on its upper surface, a shaft (33) that rotates the lower valve body (32), an air supply/discharge mechanism (35) that supplies/discharges an air pressure into/from a chamber (41) defined by the protrusion (32a) and the hollow (12b). |
