Description for Viega 18028

The Powerhead 18028 is a two position actuator for zone control which mounts on the return valve of the manifold. A 24V signal actuates the head to open the valve. The position of the valve is normally closed. The Powerhead may be used on all Brass 1" Viega heating manifolds. These powerheads are not compatible with Viega's 1-1/4" Stainless Steel Manifolds.


  • Grey cap allows for easy distinction between the brass powerhead and the Stainless Powerhead with the white cap.
  • Three indicator windows allow the position of the valve to be verified (valve is open when red bar is visible in window).
  • Compact design provides additional clearance for installation.
  • 48 in. cable length allows most connections to be made without additional wiring.

PexSupply had a great price

Comments about Powerhead for 1" Brass Manifold:

A couple of these valves have failed on my heating system so I started looking around online for replacements. PexSupply had a different Viega valve so I inquired whether they could get this one. They rapidly said "yes" and put it on their site with a great price. I ordered several to have some spares.

      The powerheads do not come in contact with system pressure, they actuate the valves on the manifold. The unit does not have a pressure rating.
