I’m trying to understand if two dissimilar discharge check valves are required downstream of a single-stage centrifugal compressor. From what I’ve read, reverse flow typically occurs during a compressor trip  in case of multistage compressors or parallel trains.

Two check valves would be reasonable. Required? I don't know. If you were responsible for NOT having two check valves and there were problems later, where would the fingers point? "Look at all this damage but he saved the cost of a check valve."
