Product Description

● Lift Check Valves

● Check Valve Installation

1) Lift check valve, a check valve whose disc slides along the vertical centerline of the valve body. The internal threaded check valve can only be installed on a horizontal pipeline. The disc can be used on a high-pressure small-diameter check valve.

2) The valve body shape of butterfly check valve is the same as that of globe valve (which can be used in common with globe valve), so its fluid resistance coefficient is relatively large. The upper part of the valve disc and the lower part of the valve cover are processed with guide sleeves. The disc guide can be lifted and lowered freely in the valve guide. When the medium flows downstream, the disc opens by the thrust of the medium. When the medium stops flowing, the disc rests on its own It drops down on the valve seat to prevent the medium from flowing backward.

3) 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.

4) For vertical lift check valves, the direction of the medium inlet and outlet channels is the same as that of the valve seat channels, and its flow resistance is smaller than that of the straight-through type.
