The difference between vertical and horizontal check valves:
First of all, from the appearance, the vertical check valve medium flow direction, that is, the check valve installation direction is perpendicular to the horizontal plane direction. The horizontal check valve is horizontal. According to the structure of the check valve, it can be divided into three kinds: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into vertical and horizontal two types. Swing check valves are divided into single disc type, double disc type and multi-disc type. The butterfly check valve is straight-through, and the above check valves can be divided into three kinds of threaded connection, flange connection and welding in the connection form.
