can you just replace the head on a honeywell motorised valve

[moogwai]

hi,got a job with a sticking motorised valve and was wonderin if you can just replace the head on it? its a pretty big system and can see it'll take ages to refill so dont wanna drain down if i can avoid it.

 

[wnjswozo]

yes,provided its only the motor thats gone,or even the syncho

 

[moogwai]

nice one, i thought so. cheers mate.

i dont think all honeywell valve heads are removeable, some of the older ones were fixed/sealed, and if you take the securing screws out the valve will come apart and mucho hep2o will come out

You could always freeze either side of valve, cut it out completly and install gate valves either side of complete new valves.
All of the above is good advice as well!

As Kirkgas said some of the older ones you cant !!!!

Swapped a few recently on the honeywells. Must of been lucky with the age.

the interchangeable heads have a slight gap between the head and body as sit on little brass studs
The older,non changeable heads have no gap and a think red flange joint..............and leak when loosened

However if you do remove one by mistake and water gushes out ,that solace in the fact the opening is a perfect size for ones thumb to cover

Just swap the motor.

The replaceable Honeywell heads have a small round lump on the metal cover - the fixed ones don't.

This is the correct way to tell. No lump means change the whole valve unless u can get away with changing the sync motor only

Hi, new to the forum. Anyway, have you never heard of "bunging it" & creating a vacume? I have an aqua vac & rarely drain a system to change a valve. Admittedly, a 28mm 1 may get the adrenalin going if it's a tight fit in the pipe-work. Who needs substances when there is adrenalin anyway

change head if casing has small lump on it , sych motor if not , last resort is bunging cos youll have 3 open ends to deal with when bungs let you down , to be totally safe drain down , dont forget youll only be draining upstairs , if house of course.

or turn the pump valve off.... 3-1=2

 

[Puddle]

then turn gate valve off on cylinder return

3-2=1

turn all rads off

3-3 = 0
