Recommendations for Pressure Relief Valve Manufacturers

[NL8]

Is anybody aware of a pressure relief valve manufacturer that can do large valves (say 6" flange connections) suitable for Hydrogen service? We are in the process of designing a liquid ring hydrogen compressor and have run into a problem sourcing a non cast iron valve that would be suitable for the application, at least in the sizes we are talking.

I'm not going to research hydrogen compatability and cast/non-cast, but the companies below make PSVs >= 6":

Crosby
Leser Gmbh & Company KG
Sempell
