Reasons for leakage during pressure testing of ball valves
Thread Content
What are the reasons for leakage during pressure testing of ball valves?
That means the valve isn’t closing properly; there is a problem with the fit between the valve seat and the sealing surface.
If there is a leak in the valve body, it is due to a problem with the valve body itself; if there is a leak at the middle flange, it is caused by the gasket or bolts. A leak at the valve stem is resulting from issues with the packing or bolts at that location. High-pressure leaks are caused by problems with the sealing surfaces, while low-pressure leaks are due to issues with the springs. Each issue needs to be analyzed on its own
