Large Caliber Bellow Globe Valves

large-diameter bellows globe valves are prone to instability during use due to the long bellows stroke, which causes friction between the inner wall of the bellows and the valve stem and affects the service life of the bellows. In addition, the flat key, which guides the stem to move axially and prevents the stem from rotating, is often easily damaged due to the increased vertical axial shear stress caused by excessive opening of the valve. According to the working conditions, a new type of large-diameter bellows globe valves is designed.
