  • Publication number: 20190316688
    Abstract: An object of the invention is to provide a method of controlling a gate valve that operates the gate valve in a short time while suppressing vibration of the valve body. A method of controlling a gate valve provided on an opening of a chamber, wherein the gate valve includes a valve body that opens and closes so as to close the opening of a chamber, a valve seat provided on the edge of the opening to which the valve body is pressed, and a sealing material for sealing between the valve body and the valve seat. The invented method is characterized in that, in moving the valve body to the open position from the closed position where the valve body is pressed against the valve seat with the sealing material compressed, the valve body is made to stop temporarily for a predetermined time at the position immediately before the compressed sealing material is pulled apart or immediately after pulled apart in the opening movement of the valve body.
