Best/favorite zone valves?

What do y'all like for zone valves, I have not used zone valves much for zoning for years as I always did not like the reliability of them as we replace many per year on service calls. But I am revisiting this now on one job that suits them well. White Rodgers, B&G, Honeywell V8043 series are ok but not really the quality I am looking for. What's your take. Tim

Service

I would guess you should already know as you stated you work in the service end.

I would use what is already weeded out and is the most common in your area. In my neck of the wood where we use atleast 95% hydronic we use HoneyWell. Every service tech stocks them and are easy to service.

After 35 years in the field I am not looking to change the world.

Thanks Ed, we do both install & service

I don't like the quick closing of the Honeywell, but the heat motor ones have had issues also. Just up in the air!

Larry (from OSHA)

take a look at

the new Honeywell 5000 series. They are similar to the ones that you see everywhere but they are slower closing. Been on the market for over a year (I think) and I have 3 on my system. They close much slower and do not bang.

Danfoss

After many years and many zone valves, we settled into using the Danfoss zone valves; the slow-opening, wax cartridge type have proven (to me) to be very reliable.

I've never tried the Caleffi zone valves, but I think they operate the same way.

Caleffi

I'll second Hot Rod. Both the Caleffi thermal and motorized valves are designed very well. Caleffi's motorized valves are also available in different voltages.

Taco EBV

My first choice is the Taco EBV, used to be called the ESP zone valve. Very reliable (I've never had to replace one yet), high CV's, and quick no tool power head removal. I put them in my house and love them. Only complaint I've ever had was in an extremely quiet house the homeowner could occasionally hear the motors open and close. But like I said, incredibly quiet house.

I trust HR even though...

some could accuse him of conflict of interest now.;-)
I'm sure the record would show he liked them even BEFORE a certain recent hiring. Kevin

zone valves

Taco 570 series simple timeless design I have used them for 30 plus years the others come and go if it ain't busted don't fix it.

Belimo or TAC

Though expensive...I like Belimo Z4 (2way) or Z5 (3-way). Can be had with on/off/floating or modulating actuators. Actuators are easy to replace, but I never had one fail in 6 years (that I know of...we had a 1 year after install controls warranty).

The other low failure setup...since I'm and old Barber-Coleman guy...is the B-C MF-22203 (MF-22323 for steam) floating actuator (which can operate on/off) mated with a 7000 series valve. The ones I have...at the building where I installed 27 of them 7 years ago and where I now work...not one actuator has failed.

The part # is complex, but FYI these were 1/2 inch 2-way, part # VF-7213-252-4-2 (1.3 Cv) or VF-7213-252-4-2 (2.2 Cv). Valve sizes up to 2 inch are available. The company name is now "TAC". These are also pricy.

take a look at the workmanship of Caleffi .

erie valves , EBV/ESP , i like also. the Taco zone valves have the distinction of being "Up-Gradeable" to I series S or R not a bad feature .

EBV/ESP

zone valves that is remarkable that you have had no failures.
I carry 4 on my truck because of failure rate of these. Like them for ease of motor changeover and very low power usage.

I'm a Taco fan

I'm a Taco fan and wish they come up with dry contact end switch like the others. I hate the white rodgers valves, too many wires to do a simple job

I've been using

Caleffi for a couple of years now. Very reliable and easy to wire. WW

For "American style" system (on my retros/ Replacements) I use the Caleffi Zonevalves. I have nothing nice to say about HW. Taco's 571 has a good track record ,The ESP from taco was not so hot. BUT I Like to use TRV's Like Oventrop,Danfooss ,On smaller Systems i use Caleffi on One pc Brass Manifolds and just screw the heads to it because it gives you the ability to Adjust flows, Purge points,Auto air vents,Shutting off of each zone,and changing Heads is easy..
