Voltage, or volts, is a measurement of the difference between two electric fields (in heating terms, the difference between the Earth's electrical field and the electricity running through your wires).
Amperage, or amps, refers to the amount of electricity flowing through the wires.
When you want the industry standard for hydronic heating applications, choose Taco's 570 Gold Series. Designers prefer these valves for their quiet and dependable operation. Installers appreciate the open lever and twist-off head that makes installation and service easy.

The seat assemblies start to leak after 3+ years. I believe that the copper bellows that keeps the piston watertight just starts to breakdown. Taco fails to redesign it. The assy. costs as much as the valve, so if you get the whole valve and take out the seat assy., you must recycle all the brass on the outside. It's a poor and costly design and not worth the trouble for the long haul.

Comments about 1-1/4" 573 Sweat Zone Valve:
In all fairness, I changed out my valve control to Taco ZVC403 and my 1st. Flr. W-R valve was not compatible. But this 573 zone vlv. works great.
Bottom Line Yes, I would recommend this to a friend

They've worked for me

Comments about 3/4" 571 Sweat Zone Valve:
As part of a preventive maintenance project I used two of these to replace the two existing Taco zone valves, of the exact same type, that were installed thirty-one years ago. The bodies are rugged so if the power heads should ever need to be replaced (and I've done only one in those thirty one years) then it takes only about five minutes to twist it onto its retaining pegs and then to reconnect the three wires. Simple.
I will always buy this product

These valves are sturdy and simple to replace power head
from Sheboygan, WI
Very easy to use, wire and install. Does what it says. Thanks Pax and TACO

Had this same valve go bad (stuck shut), it was 30 years old. I ordered this from Pex and installed it and now back up and heat is running again. Got the best price for this zone valve because Pex did a price match and gave me an extra $5.00 off...Good for me!!
Great price, fast delivery
from Markesan, WI
Product used on both hot and chilled water systems. Reliable valves and power heads. Have hundreds of them in the facility and only rarely replace the valves and the easy twist-off power heads occasionally.
What a deal
from Woodbridge, Virginia
Though I needed just the top part, I found the price so good I replaced the whole unit. When I told them that another seller had a few dollar less PexSupply matched the price. It has been working perfectly, so far! Pex shipped quickly once I reminded them that it should have been shipped a day earlier as they had promised me at the time of the sale. Wonderful people to work with and I certainly would buy it again from them.

Comments about 1/2" 570 Sweat Zone Valve:
So far so good (i.e., works, no leaks). I installed 3 of these about a week ago for my radiant floor heating system. I figured that I would change the remaining 3 of 4 after the first one leaked and was replaced by a service and another one started leaking months later.Because, I didn't want to unsolder the old valve to replace it, I removed the parts (spring, solenoid, control body) from the new valve and installed them in the body/shell of the original valve. Warning - it takes extensive force to compress the spring when re-installing the screws of the control section, so I recommend that a second person assist you. Also, I received a price-difference refund when I saw a lower price for the same valve on a competitor's website the next day, even after I had placed the order!
Great Shopping and shipping
By Norm the plumber

I use the valve in a heating system that is now 15 years old. This is a replacement for one of 6 valves. I am happy with the price and experience.
I searched for this item and found the price here to be the best. The zone vavle itself is very good. I replaced a different brand with this Taco. I have three other Taco zone valves that have been in operation for 30+ years and never had an issue with them.
