PURPOSE:To efficiently perform the multi-direction switching and cutting of the branch of a pipe by rotatably providing a spherical valve piece with multiple outlets capable of communicating to a multi-direction fluid entrance. CONSTITUTION:A multi-direction fluid entrance 4 is provided on a valve main body 1, and a spherical valve piece 2 with a fluid passage having multiple outlets 5 is rotatably arranged in it. The valve seat unit 6 with a mechanical seal structure to prevent the leakage of a fluid is provided on the inner end of the fluid entrance 4 of the valve main body 1. A pressure medium filling chamber 7 which can perform the secondary disposal is formed on the valve main body 1, thus the pressure medium can be pressurized and completely cut off in emergency. Accordingly, the multi-direction switching and cutting of the branch of a pipe mainly buried in the ground can be performed completely.
