Honeywell40003918-006 Zone Valve Power Head Conversion Kit

I took a gamble and ordered this item. It fit perfectly in my existing zone valve. I will be ordering more of these to replace all the valves.

Work good. Good fit

Item works well, however the picture is incorrect.

You can completely rebuild a Honeywell ball valve with this kit in a matter if minutes. You take the motor unit off, remove four screws, then replace the O-ring and put the new ball valve unit in place. Replace the four screws and put the motor back on, and you're finished. It's an easy fix that almost anyone can do. And, the price is right! For less than $25 you get a brand new valve!

When your zone valve doesn't work this is often all you need. What happens is the pivot gets stuck and the valve won't open or close even though the motor is working just fine. Remove the controller, make sure the water is turned off and associated valves are closed, and remove this valve with only 4 screws. The valve is easy to replace and even comes with a new "O" Ring. Tighten everything down and turn the water back on (don't forget to replace the O ring). No torches or solder needed. Now, try turning the old valve by hand and you'll probably find it's stuck. Don't try to unstick and replace the old valve as it will fail shortly after you reinstall it.I'm not a plumber, but this part has fixed my heat on several occasions, can't hurt and is way cheaper than calling a plumber.

Repair domestic hot water zone valve,worked well

This part was a perfect replacement for the internal mechanism in my Honeywell zone valve. The installation was not difficult, and the valve worked well after the valve was reassembled

Works good

This piece resolved an issue I've had with my valves allowing water to flow even when they should be closed. Replacement was pretty straightforward compared to replacing the whole assembly and a fraction of the price.

Just what I was looking for, only word of warning my original valve was fitted with brass retaining screws, very easy too break on an old fitting. Got new screw and was able to remove sheared screw from old valve body, very lucky on this occasion.

The fit was very good and it restored my Honeywell zone valve to a working condition.

To replace my Honeywell zone valve ball assembly that was seized

Good replacement for a worn out valve I had where the ball rattled. All quiet again :)
