How to detect internal leakage in a plug valve?
Thread Content
Our unit uses plug valves produced by Beijing Raymond. Some believe that whether a valve has internal leakage can be determined by the amount of waste discharged through the drain valve when it is fully open. Is this method accurate?
It can be determined, but not quantified
Thank you! According to the principle of the ball valve. The sealing performance of this type of valve should be better than that of other types
What size are the plug valves? There are also drain valves; I’ve seen these on large-diameter ball valves, but those are all ball valves with a diameter of DN400 or more
12”CL300-WCB
If a soft-seal plug valve leaks internally, it is usually due to a damaged sealing sleeve or worn-out internal components
