Taco’s new GeoSentry Geothermal Zone Valve
The Taco GeoSentry™ Zone Valve is designed to enhance the overall performance of any open- or closed-loop geothermal system by providing accurate, reliable control of exchange fields. A microcircuit-based logic is used to activate a gear-driven, electronic actuator, driving a ball valve body design.
The result is a geothermal zone valve with industry-leading energy efficiency, flow capacity, shutoff pressure rating, ease of installation and diagnostic capability. Both normally-open or normally-closed configurations are available.
Much like Taco’s Zone Sentry valve, the actuator mounts to the valve body in either direction. Snap-in quick connects on the back of the valve make for a simple, secure and fast wiring hook-up.
A green LED light shows full functionality of the valve’s operation and thermostat status. In a no-power situation, the manual override button allows the ball to be rotated up to 90°, with a slot indicating its position. A total of 12 valves can be used on a standard 40VA transformer. GeoSentry zone valves are available in sweat, threaded and three-way configurations.
