The Taco V075T2G2ZA024Q4A2 is a 3/4", 2-way, normally closed Geo-Sentry geothermal zone valve designed to enhance the performance of geothermal systems.  Operating at 24V, this valve utilizes a microcircuit-based logic to control a gear-driven electronic actuator, which drives a ball valve-based body design.  This technology leads to significant energy efficiency, with up to 93% less energy usage compared to traditional zone valves.

The valve has a flow capacity of 10.3 Cv and can handle a maximum operating pressure of 300 PSI, with a shut-off pressure of 125 PSI.  It is suitable for fluid temperature ranges between 20°F to 220°F (-7°C to 104°C), making it versatile for various geothermal applications. The Geo-Sentry valve also features universal installation orientation, allowing it to be installed in any direction except for chilled water applications.

Additional features include a multi-function LED for operational status, quick-connect wiring for ease of installation, and a manual override button for manual operation when necessary.  The valve's design allows up to 12 valves to operate on a single 40VA transformer, optimizing system efficiency.  This replaces part number 5101-G2 Zone Valve.
