Schneider Electric (Erie) VM3223 Valve Body

The Schneider Electric (Erie) VM3223 is a high-performance three-way modulating zone valve body engineered for precision fluid control in hydronic HVAC systems. Featuring a 1/2" NPT connection and a 4.0 Cv flow coefficient, this forged brass valve body is designed to deliver reliable performance in hot and chilled water applications with up to 50% glycol concentrations. As part of the Erie PopTop series, the VM3223 is compatible with AP proportional and AT tri-state actuators, allowing for seamless integration into sophisticated building automation systems requiring 0-10 Vdc or 4-20 mA control signals. The mixing body pattern ensures balanced flow characteristics, while the ANSI Class IV leakage rating provides excellent close-off at pressures up to 35 psid. This field-serviceable component allows for quick actuator replacement without draining the system, making it a staple for contractors prioritizing uptime and efficient maintenance.

Key Benefits

• Optimized Flow Control: The 4.0 Cv rating provides the necessary capacity for fan coils and baseboard heating while maintaining precise modulating accuracy.
• Enhanced Durability: Constructed with a forged brass body and a chrome-plated stem to resist scaling and corrosion in varied media conditions.
• Simplified Maintenance: The PopTop design allows for tool-free actuator removal, significantly reducing service time for field technicians.
• Broad Media Compatibility: Rated for temperatures from 32°F to 200°F, making it suitable for both cooling and heating cycles.
• System Reliability: Tested to 300 psig static pressure to ensure long-term integrity within commercial and residential hydronic loops.

Common Questions

What actuators are compatible with the VM3223?
This valve body is specifically designed to work with Schneider Electric AP (proportional) and AT (floating/tri-state) series actuators. It is not compatible with standard two-position (on/off) PopTop actuators.

Can this valve be used in steam applications?
No, the VM3223 is rated for hot and chilled water systems only. For low-pressure steam applications, refer to the Schneider VS series valve bodies.

Does the VM3223 support mixing or diverting flow?
The VM3223 is a three-way mixing valve. It is designed to take two inlet sources and provide a single outlet, ensuring consistent discharge temperatures in modulating loops.
