Taco Geothermal Zone Valves
and Replacement Heads for the Taco Geothermal Zone Valves
|
|
|
Taco Geothermal Valves are designed for high head, open system zone control.
The unique end switch design permits control of the heat pump by the valve. This allows
movement of cold water into the coil before the heat pump actually starts. Available in 3/4” threaded, 3/4”
and 1” sweat connections.
Taco Geothermal Zone Valves were created especially to eliminate noisy water
hammer. The Taco GT Whisper Guard operates in a totally different way from
fast-acting solenoids. How? It closes slowly and no water hammer occurs. The
unique end-switch design permits control of the heat pump by the valve. This
allows movement of cold water into the coil before the heat pump actually
starts. The bronze body and corrosion resistant internal parts provide for
long, trouble-free service.
