The Schneider Electric (Erie) VT2343 2-Way Flare Valve is a precision-engineered control valve designed for regulating fluid flow in hydronic HVAC systems. It controls the passage of hot or chilled water through equipment such as fan coil units, unit ventilators, and baseboard heaters, maintaining consistent temperature levels. Actuated by a compatible control device, the valve opens or closes in response to thermostat signals, enabling efficient zone control. Its compact design, reliable sealing, and easy installation enhance system efficiency, reduce energy consumption, and support consistent indoor comfort in residential and commercial applications.
