In a gate valve that opens and closes a flow path with a valve body that moves up and down in a direction perpendicular to the flow path in a valve box through which liquid flows, from inside the valve storage case that communicates with the upper part of the valve box to the seat side of the valve box. Both valve bodies are installed on guide rails erected on both sides of the cylinder to guide them, and the tips of piston rods extending from each fluid cylinder are attached to the guide rails on both sides, and each fluid cylinder is actuated when the valve is closed. A valve closing device that can press each guide rail together with both valve bodies toward the seat side.
