Description
The Schneider Electric (Erie) VT3221H13A020 3-Way Valve is a hydronic control component with 1/2″ NPT threaded connections and a 24V actuator, used in HVAC systems within chilled water and heating circuits to regulate water distribution. It operates through an internal arrangement that shifts or blends hot and cold water according to system demand, supporting air handling units, fan coil units, and chilled water piping networks. In closed-loop hydronic lines, it maintain stable flow balance, improve temperature consistency across terminal equipment.
