Description
The Schneider Electric (Erie) VM2221 is a two-way, modulating zone valve body engineered for precise hydronic flow control in commercial and residential heating and cooling systems. Designed to pair with compatible Erie actuators, this valve body delivers smooth, proportional modulation — making it an ideal solution for variable flow applications where accurate temperature regulation is critical.
Key Features
- Two-way, modulating valve body for proportional flow control
- 1/2″ NPT connections for straightforward pipe integration
- 1.0 Cv flow coefficient for reliable, calibrated flow performance
- Compact design suited for zone valve assemblies in hydronic systems
- Compatible with Schneider Electric (Erie) modulating actuators
- Durable construction for long-term reliability in HVAC zoning applications
Application
The VM2221 valve body is well-suited for hydronic heating and cooling zone control, fan coil units, air handling units, and other HVAC systems requiring modulating water or glycol flow. Its 1/2″ NPT connections allow for easy installation in standard piping configurations, while the 1.0 Cv rating ensures predictable flow characteristics across a range of system pressures.
