Taco circulator and Webstone isolation flange-valves?

Member Posts: 76
I need to replace a Taco 007-F5, and want to install isolation valves, preferably with as little fuss as possible. The inlet pipe is NPS 1.5" and the discharge pipe is NPS 1". AFAIK, Taco only sells their isolation flange-valves in pairs. Webstone makes a product (https://www.supplyhouse.com/Webstone-40406-1-1-2-IPS-Isolator-Flange) that comes individually. Can I assume that the flange on that will mate up with the circulator (with the Taco o-ring in between) and the bolt holes will match? Sure, I could do this with regular ball valves, nipples, reducer, etc., but I'd rather not if I can get an individual flange-valve for each side.
Fast. Cheap. Good.

Thank you for pointing that out. There's a reason I'm SteamFTW and not HydronicsFTW. (eye-roll at myself). It's my friend's system, an old gravity conversion, and there's only one circulator. Just heat, no IWH. I'm going to bookmark this for them when they start getting bids for a new boiler. Thank you for the photo!MikeAmann said:You should see that the ports on the circulator are both smaller than your 1" pipe.
If you don't mind my curiosity: what's the vertical rod that looks like it comes off the left-side bolt of the shut-off flange on the right?

@MikeAmann That would have been my guess, but I can't see how it attaches at the circulator. Does it connect to the flange bolt somehow?Fast. Cheap. Good.
