I need to replace some leaking pressure relief valves on some older soda kegs. They are the smaller lever-handle kind, which I think is an older Firestone model. I can't find any online catalog listing these. CHI Company shows them in a photo but doesn't list them (and doesn't answer the phone), and nobody else seems to acknowledge their existence.
If I can't replace the PRVs, I will probably have to replace the lids, or drill out the valve seats and replace with the big threaded insert PRVs (which are about the same price as replacement lids).
