The valve lifts at 125 psi is it suppose to set immediately after it reduces the pressure to below 125 or does it relief the pressure to a lower preset pressure before it closes?

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following:

This item will start to open at approximately 90% of its relief capacity. Once the pressure is relieved to that rate, it will start to close.

Replacement of PSV

Is there an industry trade practice or known standard for replacement of these air PSV's. They are too small and cheap to repair.

Answers

Answer: 
You are correct, these valves are not made to be repaired and no parts are available for them. As for an accepted industry standard on life span, we unfortunately have no concrete documentation on how long they will last due to there being too many variables on their usage.
