A friend of mine sent me these pics.
I’ve seen some really old B&G zone valves and these don’t look anything like them. They’re decommissioned on an operating radiant system, in series with two pumps in the boiler room.
Numbers on them are SDV-61.
Motorized checks?

@Steve Minnich . Are you sure it said ......"SDV-61"....and not
"SBV-61"??
I'm asking cause @Ironman threw me on this one.
I thought for sure that they are modulating circuit setter balancing valves.
But now that I read this post....?0 -
I’m not sure. That’s just the information that was given me. I was never on the job. I’m just really curious since he sent the photos.Steve Minnich0
