Taco Geothermal Zone Valves

Geothermal series Zone Valves by Taco are designed for use in geothermal systems which have high head and allow water into the coil before the heat pump starts. It's a heat-motor, 2-way zon valve with 3-wire terminal block connection, 24V power supply and an end switch. The valves are made of bronze and have a removable powerhead, which allows to service the valve without draining the system or replacing the entire zone valve.
