Erie Controls VM2222T33A00T Modulating Zone Valve Assembly

Erie Controls VM2222T33A00T Modulating Zone Valve Assembly delivers precise flow control for hydronic zoning in residential and commercial HVAC systems. This 24V, 1/2" NPT valve provides a modulating 2-way valve with a 2.0 Cv flow coefficient, non-spring return, and a 3-wire float signaling arrangement.

Engineered for reliable zone control, the VM2222T33A00T integrates with standard hydronic hardware, enabling accurate temperature balancing and energy efficiency. The 24V operation and 1/2" NPT ports simplify retrofits and new installations alike, while the non-spring return and 3-wire float interface offer smooth, modulated valve positioning for precise comfort control.

Compared to non-modulating valves, this assembly provides proportional control to match building loads, reducing pump head and energy use while improving indoor comfort. Its compact 2-way design is well-suited for tight mechanical rooms and retrofit projects. Designed for easy installation with standard piping and electrical connections, it reduces service time and ensures reliable long-term operation.
