“The Z series is a big improvement over the previous E series. They have twice as big capacitors and are very quiet. The E series could no longer completely turn off my valves after 3 years and I could hear their motors just about anywhere there was a radiator. I have big hopes for the Zs.”
“I replaced my old B&G valves with this one. It was very straight forward on what to do. Wiring was very simple. It is nice to see at a glance which one is on by simply looking at the small indicator light on the valve. My old ones did not have that and I like that feature.”
“This item should be offered without the Brass Attachment. Taco units burn out.....but the brass part is fine. So the control should be sold without the brass valve.”
“We use this valve to control glycol on our fermentors in our brewery. They are driven by temperature controlers that monitor the highs and lows of the beer we are aging. The life span of these units is many years. I have tried other manufacturers and these are the best.”
“Deceptive marketing. The 1" version of this product does in fact allow 1" pipe connections, however, the valve port is the size of a non-full port ½" valve. I didn't expect a full-port valve but I did expect at least a typical 1" valve port size. It is really too bad because this is a good valve, easy to use and swap motors but not worth the high price just to reduce my 1" pipe-run down to less than 3/8" because they cheap'd out on a valve casting. I expected more from Taco... so sad. I will install these anyways and I will just have to eat the temperature drop the added restriction will incur but I will not be using these in my next house.”
“I use this as a zone valve for geothermal heating and cooling (directs/cuts off water to a fan coil unit). The Taco model it replaced had a less powerful motor, and it would stop responding to a call if it wasn't able to reach home position (fully open or fully closed). This model is much more robust. Stronger plastic, more powerful motor, better design.”
