Honeywell Unique Valves

As this valve received a recent resurrection via the mailroom@heatinghelp.com I thought this might be of interest to others who still have a functioning Unique valve.

Wish I knew where the last remaining stock of these were hiding.

there might be some in like a barn or abandoned commercial building somewhere but the chances of them getting united with someone that knows what they are is pretty close to 0. you'd have a better chance of salvaging them from a building that is being torn down or "modernized". danfoss and a couple others make a valve with a lance that could be used in a similar way. modern valves won't allow for the series loop bypass thing.

the honeywell book is in the library on here somewhere.
