Schneider Electric (Erie) VM3221 1/2" NPT 3-Way Modulating Valve 1.0 Cv

The Schneider Electric (Erie) VM3221 3-way Modulating Valve operates as a 1/2" NPT with 1.0 Cv flow coefficient which precisely controls HVAC system fluid flow through internal position adjustments. The valve operates through control signals that determine port openness to direct or blend water or glycol fluids. The system operates in fan coil units and unit ventilators and small air handling units to manage heating and cooling efficiency. To delivers accurate temperature management which enhances both energy savings and better user satisfaction. This system enables controlled temperature adjustments through its modulating function which prevents sudden temperature shifts. The small footprint of the device together with its stable operation enables simple installation.
