The Investment Casting Screwed Globe Valves stem axis of the shut-off valve is perpendicular to the sealing surface of the valve seat. The opening or closing of the valve stem is relatively short, and has a very reliable cutting action, making the valve very suitable for cutting or adjusting and throttle use of the medium. The structure is simpler than the gate valve, and it is more convenient to manufacture and maintain. The sealing surface is not easy to wear and scrape, and the seal is good. There is no relative sliding between the valve and the sealing surface of the valve body during the opening and closing. Therefore, both the wear and the abrasion are not serious, and the sealing performance is good and the service life is long.
