Schneider Electric VT3322 3-Way 2-Position Zone Valve

Schneider Electric’s Erie VT3322 is a 3/4" NPT, three-way zone valve in the PopTop family designed for two-position (On/Off) control in hydronic heating or cooling systems. The valve body delivers a 3.0 Cv flow rating and is rated for up to 400 psi static pressure, making it suitable for residential and light commercial hydronic service where mixing or diverting hot or chilled water is required. Typical configurations pair the VT3322 body with electric actuators (for example, VT3322G13A020), providing 110–120 VAC, two-position operation with spring return and 18-inch leads; some variants also offer an integrated SPDT end switch for signaling. With 3/4" NPT connections and the Erie PopTop design, this valve supports mixing and diverting in radiant heating, baseboard, or fan‑coil systems and is part of Schneider Electric’s broader VT family that covers multiple sizes and body patterns for on/off zone control.
