Taco Z050T2 is a Motorized Zone Sentry Zone Valve with 1/2" Threaded, designed to be used in a wide variety of heating and cooling applications, provides on-off, normally open or normally closed control in both open and closed hot or chilled water hydronic systems.

Patented technology and microcircuit-based logic for controlling a gear driven electronic actuator make it the most technologically advanced zone valve ever made. The capacitor-powered valve is loaded with innovative technology and has a new high torque, high efficiency and highly reliable miniature motor. The valve can be installed in any orientation, allowing the operator to be mounted to the valve body regardless of direction. A green LED light shows full functionality of the valve.
