Schneider Electric (Erie) VM3223T33A000 Valve Assembly

The Schneider Electric (Erie) VM3223T33A000 Valve Assembly is a professional-grade 3-way mixing zone valve designed for precision fluid control in closed hydronic systems. This high-efficiency Erie PopTop valve features a 1/2" NPT connection and a 4.0 Cv rating, making it ideal for fan coil units, VAV reheat, and baseboard applications. Built with a rugged forged brass body and a 3-wire floating signal actuator, this non-spring return assembly ensures stable, fail-in-place performance during power interruptions. The 24Vac zone valve motor is equipped with a magnetic clutch to prolong the life of the gear train and a manual override lever for rapid field setup. Technicians can rely on the tool-less actuator engagement, allowing the modulating zone valve to be snapped onto the body after piping is complete, reducing installation time and preventing heat damage during soldering.

• Floating Control Signal: Compatible with 24Vac three-wire signals for precise modulating control in HVAC systems.
• High-Flow 4.0 Cv Rating: Engineered with an equal percentage flow characteristic for balanced performance in mixing configurations.
• Superior Build Quality: Features a forged brass body, nickel-plated stem, and high-temperature thermoplastic plug rated for 300 psi static pressure.
• Field Efficiency: The PopTop design allows for one-handed actuator removal and replacement without breaking the hydronic seal.
• Operational Reliability: Fluid temperature range from 32°F to 200°F ensures compatibility with both chilled water and hot water loops.

Common Questions

Can this valve be used in steam applications?
No, the VM3223T33A000 is specifically rated for water and glycol solutions (up to 60%). It is not recommended for steam service.

What is the close-off pressure for this 1/2 inch model?
This assembly provides a maximum close-off pressure of 35 psi, ensuring tight shut-off and minimal leakage in standard residential and commercial zones.

Does this valve return to a zero position if power is lost?
This is a non-spring return zone valve, meaning it will remain in its last position if the 24V supply is interrupted.
