The check valve of the lift check valve series is a check valve that slides along the vertical centerline of the valve body. The lift check valve can only be installed on the horizontal pipe. The valve ball can be used on the small-diameter high-pressure check valve. . The upper part of the valve flap and the lower part of the valve cover are processed with guide sleeves, and the valve guide guides can be freely raised and lowered within the valve guide guides. When the media flows downstream, the valve flaps are opened by the medium thrust. When the medium stops flowing, the valve flaps itself. The vertical drop falls on the valve seat and acts as a counter-current to the media. The shape of the valve body of the lift check valve is the same as that of the shut-off valve, so its fluid resistance coefficient is large.

The lift check valve can be applied to water, steam, and gas. The elevating stainless steel check valve can use corrosive media, food, oil products, and medicines.
