Caleffi

Caleffi makes a great zone valve with union ProPress connections. I like the unions because if you ever need to change out the valve, just loosen the unions and remove the old valve and put in the new one. Boom shaka laka!

I would love to see these unions on their other devices that have either ProPress, solder or threaded connections. Fill valves, air eliminators, dirt separators.........

    Thanks for noticing, here are some of the tailpieces we offer, a 1961 pex expand fitting is on it's way, Upon, Rehau, etc..

    These tailpieces fit at least 12 of our products now, you can buy zone valves, mixing valves, balance valves, fill valves, etc as bare bodies and select tailpieces.

    Also mix and match connections, sweat on one, pex on the other, etc. A 3 way mix valve could have different connections or all 3 ports.

    How about microbubble air eliminators?

    Does this mean we can buy one body that can be fitted with different size connectors?

    This multi position version could have any of those tailpieces added 1/2- 1" for now. I don't think this body is large enough for 1-1/4", yet.

    I've been using the Caleffi zone valves almost exclusively for about 2 years now, I love them. Glad to see the union connectors are available on more than the ZVs now!
