    Danfoss and a few others make a valve with a lance you could probably retrofit.

    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.

    Oventrop makes or made a single entry radiator valve. I've used them to convert cast radiators where holes where floor penetration was limited.
