A valve plate with a large diameter semicircular groove on both ends and a recess on the outer periphery is arranged, and the groove passing through the center is aligned to form a hole for the valve stem, and the large diameter semicircular groove is used to insert a rubber sheet. A valve body made by spot welding a valve plate to a core metal plate, sandwiching a large diameter part of the ring with a valve stem through hole and a rubber seat ring in a recess on the outer periphery, is placed inside the valve box. Insert the valve stem through the valve stem insertion pipe provided on the outer circumference of the upper part of the box, press it into the valve stem hole in the center of the valve body, and insert the tip of the valve stem into the valve stem support provided on the lower side inside the valve box. A butterfly valve made of
