Marine Cast Iron Lift Check Globe Valves

The Marine Cast Iron Lift Check Globe Valves automatically opens and closes the valve disc depending on the flow of the medium itself, ensuring that the medium can only flow in one direction. When the medium flows forward, the valve disc opens under the action of the medium pressure to allow the medium to pass; when the medium flows back, the valve disc closes under the action of its own weight and the backflow pressure, thereby preventing the medium from flowing back. The Marine Cast Iron Lift Check Globe Valves is mainly composed of valve body, valve seat, valve disc, valve cover and other related components. There is a guide rod on the valve disc, which can be lifted freely in the guide hole of the valve cover. When the medium flows forward, the pressure below the valve disc exceeds the pressure above it, pushing the valve disc up along the center line of the guide hole of the valve cover, and the valve opens automatically; if the liquid flows in the opposite direction, the pressure above the valve disc is greater than the pressure below it, and the valve disc is clamped on the valve seat, thereby preventing the medium from flowing back.

Simple structure and easy maintenance: The valve disc moves up and down along the center line of the valve body, with a simple structure and easy maintenance.

Wide range of application: Applicable to various fluid media, including water, oil, steam, etc., and suitable for different temperature and pressure ranges.

‌High reliability‌: Automatic opening and closing is achieved by medium pressure and deadweight, no external energy is required, and the reliability is high.

‌Installation direction is critical‌: During installation, it is necessary to ensure that the opening and closing direction of the valve disc is consistent with the medium flow direction to ensure normal operation‌.

Marine Cast Iron Lift Check Globe Valves are widely used in ship water supply and drainage systems, fuel systems, lubrication systems and other occasions where medium backflow needs to be prevented. Its reliable one-way flow characteristics ensure the safe operation of ships under different working conditions‌.
