PURPOSE:To enable selective feeding of fluid from a main pipe port to branch pipe ports through the rotation of a valve body by providing a connecting port in the valve body, more than one branch port radially on the sides of the valve proper which freely rotatably incorporates the valve body, and a main pipe port on one end face of the valve proper. CONSTITUTION:On starting a pump (not shown in the figure) connected to a main pipe 11, a fluid is sent from the main pipe 11 through a main pipe port 9 of a valve proper 2, and a connecting port 13, a branch pipe port 8, and a branch pipe 10 of a valve body 3, to, e.g., a first washing process connected to the branch pipe 10. When washing is completed, a driving shaft 5 of a motor 4 is turned due to specified starting signals, causing the valve body 3 and a rotary disk 6 to rotate through a holder 16. When they are turned by 90 deg, one of the striking projections 18 hits a limit switch 7, which transmits signals to cause the motor 4 to stop. Thereby the connecting port 13 of the valve body 3 is connected to a branch pipe port 8' which is connected to, e.g., a second washing process, sending the fluid from the main pipe 11 to the second washing process. |
