Stadler PH 24 zone valve power head

gjkris

Looking for a source for PH 24 power head. All information I have gathered indicates they are no longer in production. Is there a replacement? Does anyone have old stock? Help, please.------------------gjkris

This should work to replace it:

Caleffi may work also. Hot rod can verify that.

Did it come out of that RTI box behind it?

It is a German valve, so not one that Caleffi manufactured.

Sometimes inside you may find a manufacturers logo or name.

What you will find it the threads are common across the brands, so most any actuator will attach.

The small difference will be the pin length on the valve part, and the stroke length of the actuator.

What can happen if you don't check is the valve can be held partially open when it is powered off, or it may not stroke far enough to fully open.

Really need to check that tolerance if you switch brands.

In some cases we send an adaptor ring when the Caleffi brand is used on OEM manifolds..

Stadler is now owned by Viega. There is a new powerhead available from Viega that will fit by using an adapter ring. Call Viega tech support and explain what you're looking for to get part numbers. 800-976-9819

Viega part number 15065 will allow you to use a viega powerhead on those old brass Stadler manifolds.
