Hunter PGV Diaphragm

I have a Hunter PGV that has blown 4 diaphragms in the last month. The system is 13 years old and I started having diaphragm issues last year. I have replaced almost all of them with no issue but one zone just keep blowing them. Bad batch, bad control valve top, or just bad luck?

Are the diaphragms actually getting a hole in them? Are they older diaphragms?
Where did you buy them?
What is the valve doing that makes you think the diaphragm is bad?
