Lift Check Valve DN80 PN40 CF8

Lift Check Valve: a check valve with the disc sliding along the vertical centerline of the valve body. The check valve with internal thread can only be installed on the horizontal pipeline, and the disc can be a ball on the high-pressure small-diameter check valve. The shape of the valve body of the butterfly check valve is the same as that of the Globe Valve (it can be used in common with the globe valve), so its fluid resistance coefficient is larger. Its structure is similar to the globe valve, and the valve body and disc are the same as the globe valve. The upper part of the valve disc and the lower part of the valve cover are machined with guide sleeves. The valve disc guide can be freely lifted and lowered in the valve guide. When the medium flows downstream, the valve disc is opened by the thrust of the medium. It falls vertically on the valve seat to prevent the reverse flow of the medium. The direction of the medium inlet and outlet channels of the straight-through butterfly check valve is perpendicular to the direction of the valve seat channel; the vertical lift check valve has the same direction of the medium inlet and outlet channels as the valve seat channel, and its flow resistance is smaller than that of the straight-through type.
