[Question] Common Valve Failures

[Question] Common Valve Failures

[Question] Common Valve Failures

(OP)
I am working on a small project for my company who uses various Valves in a production line.  What are some of the common failures for valves such as Gate Valves, Ball Valves, Check Valves, etc?  I will be compiling a 'cause code' sheet to fit in with the Root Cause Analysis project, so breaking down failures to specific areas of the valve would be appreciated!  I'm going to start off with the little pieces I have gathered so far, please feel free to let me know if I am on track.

Seals > Right material
Fasteners > Right material and size

(I've seen strange things)

RE: [Question] Common Valve Failures

Using a ball or gate as a flow regulator.
Seal and seating failure.
Leakage through packing.
Cavitation.
Controller gain on a control valve turned up too high.

You'd do better to ask this in the tech forum for Valves.  This forum sure isn't the right place.
