Analysis of damaged valve diaphragm

This post was last edited by sdwfsgyykai on 2018-5-9 at 14:23. The diaphragm only developed cracks after half a year of use; there is no wear, and the spring is in good condition. It’s not clear what caused this, so please share your analyses
Natural aging? Has it been in the warehouse for a long time? Or is the intake pressure too high?
The image doesn’t appear; it’s not visible. The screws used to secure the diaphragm are tightened too much, and the uneven force applied creates stress, which results in the edges of the diaphragm being damaged. Additionally, if the valve remains in one position for an extended period of time, problems will arise. If it’s not a problem with the diaphragm material, then it’s one of the issues I mentioned above
The intake pressure isn’t high; over time, the diaphragm might have problems
