Powerhead for Brass Manifolds
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.
Features
• 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.
