I do not believe any other manufacturers make a Listed normally closed monitored butterfly valve. This is a NFPA 20 requirement. John John August Denhardt, P.E.

Like in Nibco’s catalogue, you have to order the N suffix or something like that? Assuming yes, all that means is that it’s a regular, everyday fire protection butterfly valve but the tamper switch kit is factory-wired for NC service. So if your question is about the tamper switch, yes you want normally closed ones for a flow meter/test bypass. I think.

Or can they be just be monitored butterfly valves.
