Description
The Schneider Electric (Erie) VM3213T33A000 3-Way Zone Valve 1/2″ Sweat NSR 4.0Cv is a fluid flow limiting element optimized to regulate hot or chilled water distribution within hydronic circuits, ensuring accurate temperature control and balanced system operation. It works by modulating or directing internal passageways based on electrical input, allowing controlled mixing or diversion of fluid paths for stable output conditions. Placed within HVAC systems in fan coil units, air handling units, or heating loops, it integrates with actuator controls to maintain coordinated flow regulation. Its application supports precise thermal management and improves system responsiveness.
