Schneider Electric (Erie) VM3221 Valve Body

The Schneider Electric (Erie) VM3221 Valve Body is a robust 3-way mixing assembly engineered for precision in hydronic HVAC systems. This 1/2" NPT zone valve features a 1.0 Cv flow coefficient, making it ideal for managing low-flow terminal units such as fan coils and baseboard heaters. Constructed with a durable forged brass body and rated for 300 psig, this unit is built to withstand demanding commercial and residential piping environments. The VM3221 modulating valve utilizes Erie PopTop technology, which facilitates rapid actuator replacement and reduces maintenance downtime for field technicians. It is compatible with water or glycol solutions up to 60% concentration and offers a tight ANSI Class IV leakage rating to ensure maximum system efficiency and climate control accuracy.

• Enhanced Flow Control: The 1.0 Cv rating provides stable modulating performance for balanced hydronic distribution.
• Field-Proven Reliability: Features a high-temperature thermoplastic plug and a chrome-plated stem for long-term operation in chilled or hot water systems.
• Simplified Installation: Standard 1/2 inch female NPT connections allow for direct integration into existing North American piping headers.
• Modular Design: The PopTop actuator connection allows for quick-release servicing without breaking pipe seals.

• Is the actuator included with the VM3221? No, this is the modulating valve body only. You must pair it with a compatible Erie PopTop actuator (tri-state or proportional).
• What is the maximum static pressure for this valve? This Erie zone valve body is rated for a static pressure of 300 psig and a maximum media temperature of 200°F.
• Can this be used for steam applications? No, the VM3221 is specifically designed for liquid hydronic service and is not rated for steam use.
