Mixing valve with ODR

ultimatedesi

Hello,

I am facing issues procuring TACO iSeries 1" mixing valve with ODR (I100T3R-1) in NJ 07836. Seems all the suppliers I have tried are showing the valve on backorder. I would like to request suggestions on: 1) If there is any way to procure this item at a reasonable price (a vendor in Canada was willing to ship at nearly double the price!) and more importantly 2) what are other equivalent alternatives that should be considered please.

Appreciate your help. Thanks.

Thanks, Snowmelt and EdTheHeaterMan for your quick response. I have reached out to the store through their website and would see if they have the 1" version. Meanwhile, am open to suggestions on alternates as well. Thanks.

Are you sure you need a 1”, looks like the cv is higher on some 3/4, other versions are very close Cv.
How many gpm are you flowing?

Better screen shot, Cv and weight

This valve will feed 2 zones (total 14 ports with around 270'-280' long 1/2" dia.tubing).

A smaller valve than the piping it is connected to is actually desirable . You want to use the valve which has a CV rating close to your flow rates . These smaller valve will reach target faster because less water flows through them .

in the standard 3 way, both 3/4 and 1” have 4.5 Cv, should handle 40- 50,000 btu/hr
The 1/2 may be a best choice as Rich mentioned. Really don’t want to oversized a ball type control valve.

@hcpatel - total 14 circuits, each of them 270/300 feet long.
@Rich_49 - the circuit is 1" with all pumps/manifolds and leads with 1" pipes.
@hot_rod - seems CV is same (4.5) for 1" and 3/4" 3-way models.. or am I not reading it right?
Thanks

You could install one of these as a fixed position mixing valve which should give you an outdoor reset curve that is parallel to the boiler curve. If you decide you want individual outdoor reset, you could add a powerhead and controller.

@hot_rod and @Rich_49 do you think the temp will be stable as the flow changes with one vs two circs running?

hot_rod

Here is the pressure drop with 14 loops at .5 gpm each? (7 gpm) use the 3rd box to see the pressure drop at 5.6' head, acceptable.

But I only see 8 loops on the mix valve? if so 4 gpm, which is fine for a 4.5 cv valve.

There are reducing couplings . The smaller valves are more accurate . SupplyHouse. com can get you the 4 way ODR 3/4" between December 9 - 16

The smaller the valve you use will be more stable when circs turn on and off . That's kinda why we mentioned using the smallest valve . You should call me to have a look , I may have the valve body for a 3/4 or 1 " around the shop . You'll probably be able to get sensor and actuator . Call me , I'm in Toms River and may actually be able to get you one , a customer of ours has spare everything in multiples at his house , maybe he would part with one now if it's replaced .
