Easy Install and saved us money!
Helped fix our boiler without spending a lot of money to have someone come out. Make sure you know how to work on electrical work but other than that it was very easy to install.

Great Substatution (so far)
Installed on boiler system. Installed quickly, and functions as per specification. Recent installation so I can not verify longevity of service as of this review.

Great customer service
Died after 6 months but seller shipped a replacement promptly. 4 stars because of hassle of opening PC a 2nd time. Customer service was 5 star

Better than original
I've been a handy man for many years. I was surprised to find this well-built piece in the box. Packed new in original carton and a heavier duty unit to boot. I found it to be much better than the Honeywell. Fit as well as function is perfect. Sorry, the thieves lost on this one! Thanks to Amazons next day delivery, all is great! Perfect!

Good replacement for the actuator heads for the Honeywell V8043 zone valves
Good replacement for the Honeywell zone valve with end switch (4 wires, 2 motor wires and 2 end switch wires). Easy to install (assuming the original contractor did not overtighten the screws...)

A satisfactory replacement for the brand name product
Essentially the same as the Honeywell powerhead for which it is a drop-in replacement. Well built, and so far is working fine.

Easy to replace
My old Honeywell operator died. This came fast and was easy to install with no issues. The cost was fair. I’ve bought just the actuator in the past but this time needed the end limit switches and this fit the bill.

Excellent Value Replacement for Honeywell
This is my second purchase of this model. My system has 3 zones. The first one was purchased in 2019 and still operates like it should. I made this purchase to replace another HW that went bad. I will be getting a 3rd to keep as a spare as well. These are not garbage knockoffs... Are they cheap compared to others? Yes. Do they work as they should? Yes. Do they last? Mine has. Very easy to replace, 2 screws and 4 low voltage wires. This unit can also replace your powerhead that has the screw terminals on top.

Much like the other reviews, I used this part to replace a Honeywell Powerhead that was 27 years old. The replacement instructions are clear. The product itself is of good quality, and fit perfectly. I just hope I can get similar "mileage" as the original!

It is easy to install and works. Will add review if it works for over a year.

I have 3 zone valves. This actuator is not built as well as the other two but is the same as the original. This style has a thinner gear plate and appears to run off the central path over time and deforms... thus having to replace it more often. Note: this complete valve package was inferior to the other 2 thus needing to buy another inferior actuator that mated with the valve body.

This power head fits the Honeywell valve perfectly and costs much less than the Honeywell , if it can be gotten

Un moteur de qualité pour remplacer un original Honeywell à une fraction du prix. Simple à chamger.
