First off, this is not a bad post regarding Eaton compressors; they've been great at trying to help fix this problem.
I bought Eaton's 5HP dual stage pump that I put on top of an 80 gallon tank; it's almost 2 years old. I have a inter-cooler, water separator and electric air dryer connected in series between pump and tank. The compressor is outside in an enclosure, but plenty of opening for cooling air. I'm using this check valve that I purchased new: https://www.amazon.com/gp/product/B003H800RK/?tag=atomicindus08-20
The problem is after prolonged continuous run situations when I'm doing sandblasting, the second stage safety relief valve starts popping. This compressor is capable for continuous run per Eaton. The valve doesn't pop during regular use when cutoff (150psi) point is reached. So, I'm deducting is when the system gets hot.
Eaton has sent me 2 new 200 psi pop off valves and new second stage intake/exhaust valves. I've R&R'd both; still doing it.
Any suggestions on what to look at next?
