The Taco zone Sentry® zone valve enhances the overall performance of any zone valve system. The unique patented technology in the zone 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 zone valve that leads the industry in energy efficiency, flow capacity (Cv), shut-off pressure rating, ease of installation, diagnostic capability and the number of valves that can be use on a standard 40 VA transformer.
