置。 The valve body has an axis that intersects with the axis of the valve box, and is rotatably built into the valve box, and the movable part of the cylinder, which is attached to the valve box via a holding member, and the valve stem are power transmission members. In the cylinder-driven butterfly valve, the outer circumferential seat portion of the valve body, which is connected to each other via the cylinder and is rotated together with the valve stem by driving the cylinder, opens and closes by contacting and separating the outer circumferential seat portion of the valve body from the inner circumferential seat portion of the valve body. A cylinder-driven butterfly valve characterized in that it is provided with an end position adjustment mechanism that interferes with either the movable part or the power transmission member at the adjustment position to set the stroke end position of the cylinder in the valve closing direction. Closed position adjustment device.
