Schneider Electric (Erie) VT3322G13A020 Valve Assembly

The Schneider Electric Erie VT3322G13A020 is a commercial-grade 3-way zone valve designed for demanding hydronic heating and cooling applications. Engineered for precision flow control, this 3/4 inch NPT assembly utilizes the industry-standard Erie PopTop actuator system, allowing for quick head replacement without draining the entire system. Operating on a 24Vac power supply, the unit features a two-position (Normally Closed) configuration with a spring return mechanism, ensuring the valve returns to its fail-safe position during power loss. With a 3.0 Cv flow coefficient, it provides the necessary authority for balanced flow in fan coil and baseboard radiation circuits. The actuator delivers a rapid power-stroke of 9 to 11 seconds and a spring return time of 4 to 5 seconds. Rated for fluid temperatures up to 200°F and housed in a NEMA 1 enclosure with an 18-inch appliance cable, this valve assembly is built for consistent performance in high-cycle environments.

Key Benefits for Contractors:

• Streamlined Installation: The 3/4 NPT connections and 18-inch lead wires reduce field wiring and piping time.
• Serviceability: The Erie PopTop design allows for tool-free actuator removal, simplifying future maintenance and troubleshooting.
• System Reliability: High-temperature rated construction handles fluid ranges from 32°F to 200°F, ideal for diverse HVAC loops.
• Fail-Safe Operation: Mechanical spring return ensures positive shut-off or bypass during power interruptions.
• Compact Footprint: Designed for tight mechanical closets and plenum installations where space is limited.

Common Technical Questions:

What is the maximum differential pressure for this valve?
The VT3322G13A020 is designed to operate effectively against standard system pressures found in residential and light commercial hydronic zones; always verify pump head pressure does not exceed the close-off rating for a 3.0 Cv valve body.

Can the actuator be replaced without removing the valve body?
Yes, the Erie PopTop actuator is designed to snap off the valve body, allowing you to replace the motor and drive assembly without breaking the pipe seals or draining the system.

Is this valve suitable for potable water applications?
This Schneider Electric valve assembly is specifically designed for closed-loop HVAC systems using water or glycol solutions and is not intended for use in domestic potable water lines.
