Reasons for Valve Leakage and Solutions
Leakage Caused by the Falling Off of Closing Part Reasons: Poor operation causes the closing part to jam or exceed the top dead center, damaging or breaking the connection. The closing part connection is not secure, leading to loosening and falling off. The selected connection materials are unsuitable and cannot withstand the corrosion of the medium or mechanical wear.

What does the arrow marked on the valve body mean?
The arrow marked on the valve body indicates the recommended pressure-bearing direction of the valve, not the direction of the fluid flow in the pipeline. For valves with bidirectional sealing capabilities, the arrow may or may not be marked. If marked, it points to the recommended pressure-bearing direction, as one of the two possible directions—either horizontal or vertical—will usually offer better performance.
