120 volt zone valve

in THE MAIN WALL
I am looking for some 1 1/2" and 1 1/4" 120 volt zone valves.
They would be simple N/C non modulating valves, no end switches needed. The 1 1/4" valves will have flow rates of 10-20 GPM, The 1 1/2" 28 GPM.
They are for garage unit heaters, if figure it is easier to wire in parallel with the fans than set a transformer and relay.

    Can you use a solenoid valve. Don't know about the flow rates but sporlan would.

    Do they make non refrigerant models?

    Yes I have one for my beach house because my wife wouldn't crawl under to shut off the water it's only 3/4 " but I know they have larger pipe size.

    All make line voltage electronic valves.

    There are line voltage ball valves as well

    I was hoping to find something in the zone valve price range.

    Caleffi has an 1-1/4 Cv 7.5. That would handle the 10gpm

    Wonder if properly piped you could parallel two. We do that with TMV and PRVs

    Not my favorite ZV but these block head White Rogers have high Cv, add a transformer at the valve perhaps?

    Amazon has 110 Volt motorized 1 1/4" ball valves

    An xfmr and 2 parallel 1" valves like a taco zone sentry might be the least expensive and simplest option to get a high cv

    It would be easier to mount a small xfmr in a knockout in the control or motor junction box and run tstat wire to the valve than to run flex to the valve anyhow.

    They're not "name brand" per se, but in the past I've used some of the 2" line voltage solenoid valves from electricsolenoidvalves.com and they've been great so far. If I remember correctly they're good for 30+ GPM, we've got them in on quite a few commercial feedwater systems. Price point is on par with a 24V zone valve

    I think a Belimo B225+LF120 might be your best bet - CV of 30 and its a little more than a typical zone valve but its not bad. Pipe size is 1" so you could reduce to that. It looks like EnergyControl.com might be a good bet.

    @Matt_67, I think that is the best option, thank you.
    This building uses that Belimo valve with modulating actuators in other areas so the techs should be comfortable working on them.
