The Taco Geo-Sentry Zone Valve enhances the overall performance of any geothermal system.
The unique patented technology in the Geo-Sentry utilizes a microcircuit based logic to control
a gear driven electronic actuator which drives a ball valve based body design. All this adds up to
a geothermal zone valve that leads the industry in energy efficiency, flow capacity (Cv), shutoff
pressure rating, ease of installation, diagnostic capability and the number of valves (12) that can
be used on a standard 40VA transformer.
