Leakage in the diaphragm of the control valve
Thread Content
One of the company’s control valves has a small hole in its cylinder diaphragm, causing air leakage. Can it be taken apart to fix the leak and continued to be used? Has anyone among you dealt with a situation like this before?
Just buy a diaphragm, right? It probably won’t help to fix it. . . Take a picture and see if it can help you
This valve is quite important, but there are no spare parts available; it is manufactured abroad by the original manufacturer, and the lead time for procurement is long. It hasn’t been taken apart for a photo yet
You can fix it by taking it apart, but once you take it apart and put it back together, it’s likely to leak again
I thought those diaphragms were made of rubber, so they should be repairable.
Do you want to repair it or remove it? So it’s better to decide that after you shut down the machine and such. The diaphragm should be able to work

It definitely can’t be repaired; even if it is repaired, there’s no guarantee it will work properly. Since this valve is imported, it indicates that this location is quite important, so it’s better not to try to repair it. If it leaks again after repair, the responsibility will lie with you.
The management has decided to first order a complete set of actuators from domestic manufacturers, using the existing valve bodies; it’s not clear how fast the customization process will be
It hasn’t been repaired before, but it should be possible; tires can be repaired, and the requirements for this are much lower than those for tires.....
It’s better to purchase replacement diaphragms from the original manufacturer; otherwise, it will still affect future use, so it’s better to get it done properly from the start
