Works great
We used these controls to upgrade a pneumatic system to a digital system. Part was easy to install, and works like we hoped it would. Very satisfied and will use these again!

Taco Z075C2
Used to replace failing electronics of E075C2 - plug compatible (had to turn the connectors 180 degrees), no problems. Only had to replace the controller - not the valve. Delivered quickly. The E075C2 didn't always fully close - this controller does.

Taco Z075C2, 3/4" Sweat Motorized Zone Sentry Zone Valve
Earlier model was not good needed to replace it every year. I found the Taco Z075C2 model from Petuniverse.com & in less than a week it came. This model works good & replaced it without any problems.

Replacement for E075C2
I had problems with previous model of the valve, that got damaged after only 4 years of usage. I saw that the model was not longer available and it was replaced by the Z075C2. I bought them from Petuniverse.com, and literally in 2 days I got delivered to my home.The model is more solid, better construction and smooth operation. I replaced 4 without any problem (just the operator, keeping the old valve), and had no issue at all replacing the old model.

Excellent new version
"I used this as replacement for Taco E100C2-3, with no apparent problems. Old part was great, this is a bit more flexible, so slightly better and a great product."

I have a boiler system in my house which has (3)TACO ESP O7C52-1 ZONE VALVES AND ONE ZO75C2-1 by heating company to the tune of 385.00, 220 for valve alone. QUESTION: How complicated is it to replace the ESP07C52-1 with the ZO75C2-1? Something I can do my self with out draining system etc. To the Heating guy about 5 minutes to replace the last one.
Helpful? Yes No
The procedure would involve removing the old valve and installing the other in it's place and connecting the wiring. Since ESP has sweat connections, you would have to drain the system, unsolder the old valve and solder the new one in place. Alternatively, you may cut off the section of the piping with the old valve installed and use a copper coupling and a piece of copper pipe to install the new one.
