Tip & How-To about Heating & Cooling
You need a new Honeywell Zone Valve and you are confused by the different numbers of the valves. Let me explain a bit to help you sort through the differences.
The first thing is the V8043 number. This number is the same for the straight through two way valve body configurations. The next letter for most heating system zone valves is the one that is confusing sometimes. Usually it will be an E or a F. There are other Letters but they are not nearly as common for home heating.
This is the E valve
This is the F valve
The thing to remember here is that the E letter tells you that the zone valve has the 4 - 18” wires coming out of the motor. And the F letter tells you that the motor has the 5 terminal board on it. They can be interchanges but if you have one type already installed and you go to replace it you will have to do some figuring to know how to hookup the motor correctly. If you replace your valve with the same letter valve you will just be able to hook it up again as it was.
Then, as far as the last four numbers go, they just tell you what size pipe the valve is for.
If you need to replace the zone valve motor you can check the pricing for a replacement motor or complete head, but I have found that many times the best pricing will be to buy the whole valve and then just take the head off of the new valve and switch it with the old one.
