They both do the same job. The Hoffman is rated for high enough temp for steam. Don't know about the Conbraco

Not familiar with the Conbraco. From what I see online, it appears to a simple non-adjustable vacuum breaker.
The Hoffman is a spring loaded adjustable vacuum relief valve. This has a pair of adjusting nuts allowing you to set the break point at which the valve will open to allow atmospheric air to enter to prevent going to a higher vacuum.
Also, the Hoffman has a renewal O ring on the valve stem.
Nothing is listed about either valves venting flow rate in terms of CFM.
If something better is needed, let me know. Attached is a file on Vacuum Sentry vacuum relief valves. I think they're better, but it depends on what you really need.
The attached files have details.
