Description
Product Overview
The Schneider Electric (Barber Colman) M220A01 is a two-position, normally closed ball valve actuator engineered for reliable on/off control in commercial and light industrial HVAC hydronic systems. Operating on 24V power, this actuator delivers consistent, repeatable performance with a built-in spring return mechanism that ensures the valve returns to the normally closed (fail-safe) position upon loss of power — a critical safety feature for building automation and hydronic control applications.
Key Features
- Two-position (on/off) control action for straightforward open/close valve operation
- Normally closed spring return action — fail-safe closes valve on power loss
- 24V operating voltage for compatibility with standard HVAC control systems
- 50-second powered stroke timing for smooth, controlled valve actuation
- 35-second spring return timing for reliable fail-safe response
- Includes 10-foot plenum-rated cable for code-compliant installation in air-handling plenums and ducts
- Designed for use with compatible Barber Colman / Schneider Electric ball valve bodies

Why Choose the M220A01
The M220A01 combines Schneider Electric’s proven Barber Colman actuator technology with a plenum-rated cable, making it a code-friendly, drop-in solution for commercial HVAC installations. The normally closed fail-safe action protects equipment and building systems during power interruptions, while the 24V input ensures broad compatibility with existing control wiring. The clearly defined 50-second stroke and 35-second spring return timings allow for accurate system commissioning and sequencing.
