Replacing Head on Honeywell 272848 Valve

Postby j1ll » Tue May 15, 2012 3:11 pm

I believe that 272848 is the same product as V4043H1056.

ref ... -p-87.html

I am trying to replace the powerhead with 40003916-001, which is a replacement powerhead matching this valve according to the instructions with the powerhead and this url ... -p-85.html

I have removed the 2 screws attaching the old powerhead to the valve and expected the head just to lift off, but it seems to be firmly secured around the activator mechanism. Is there something else I need to do before I can remove the head?

Many thanks for any help anyone can give.

Simply Build It

Are you sure that your old valve is the type with a removable head? If it is, there will be a small "bump" on the top of the metal cover - the new actuator will have one.

If there is no "bump" you will have to drain down and modify the existing valve body using a plate and ball assembly kit - part no 40003918-006.

If there is a "bump", try locking the lever in the MAN position before removing the head.

Thanks for the advice.

The problem was moisture corrosion (which i think is also why the valve has failed).

Just needed more force to get the Powerhead off.
