A high temperature gate valve includes a valve body, a valve element configured to open and close a flow path, and a guide member which is provided in the valve body and guides the valve element in an opening/closing direction. The valve body includes a valve body main portion and a bonnet portion. The valve element slides along the opening/closing direction guided by the guide member. The valve element at a shut-off position blocks the flow path by projecting into the valve body main portion, and at an open position retracts into the bonnet portion. The guide member is divided into a plurality of divided guiding elements along the opening/closing direction, and each of the divided guiding elements are welded to an inside of the valve body. |
