Scope of Application for Check Valves
Based on their structure, check valves can be classified into three types: lift check valves, swing check valves, and butterfly check valves. Lift check valves can be further divided into vertical lift check valves and horizontal lift check valves. Swing check valves are categorized into single-disc, double-disc, and multi-disc types. Butterfly check valves are of the straight-through type. In terms of connection methods, the above types of check valves can be threaded, flanged, or welded.The main check valve product names of China Check Valve Network include:Wafer Silent Check Valve，Chute Rolling-ball Check Valve，Flange Swing Rubber Disc Check Valve，Oversized Silent Check Valve，Flange Ball Check Valve，Check Valve News
Horizontal lift check valves should be installed on horizontal pipelines, while vertical lift check valves and foot valves are generally installed on vertical pipelines, with the medium flowing from the bottom up.The installation position of swing check valves is not restricted; they are usually installed on horizontal pipelines but can also be installed on vertical or inclined pipelines.Check Valve manufactor
When installing a check valve, special attention must be paid to the direction of medium flow. The normal flow direction of the medium should be consistent with the arrow direction indicated on the valve body; otherwise, the normal flow of the medium will be cut off. Foot valves should be installed at the bottom end of the suction pipeline of the water pump.Therefore, vertical lift check valves and foot valves can be installed on vertical pipelines, with the medium flowing from the bottom up.
