Schneider Electric (Barber Colman) M322A01 Actuator

The Schneider Electric (Barber Colman) M322A01 Actuator is a robust 24VAC floating control actuator engineered for precise modulation in HVAC ball valve assemblies. As a spring return actuator, this unit ensures a normally closed (N/C) fail-safe position during power loss, making it a critical component for VAV reheat coils, fan coil units, and chilled water systems. This model serves as the official direct replacement for M122A01, offering a seamless mechanical and electrical upgrade without the need for additional linkages.

Designed for professional contractors, the M322A01 features a pre-installed 10-foot plenum-rated cable and an integral 3/8-inch conduit connector, streamlining installation in tight plenum spaces. Its rotary mechanical movement is optimized for SmartX VBB/VBS valve bodies, providing high-torque reliability and an ANSI Class IV seat leakage rating. With its NEMA 2 protection and RoHS compliance, this SmartX actuator delivers stable, long-term performance in demanding commercial environments.

• Fail-Safe Logic: Features 24V spring return functionality to return to a normally closed position upon power interruption.
• Universal Compatibility: Specifically designed as the Barber Colman M122A01 replacement for VBB and VBS series ball valves.
• Rapid Installation: Equipped with a 10' plenum cable and a tool-free "PopTop" mounting design for simplified field service.
• High Rangeability: Supports greater than 300:1 rangeability for precise flow control in hot and chilled water applications.
• Durable Construction: Built with a thermoplastic housing and a robust gear train featuring stainless steel bearings.

Is the M322A01 compatible with my existing M122A01 setup?
Yes, the M322A01 is the direct, upgraded equivalent to the M122A01. It fits the same valve bodies and utilizes the same 24V floating control logic, allowing for a drop-in actuator replacement.

Does this actuator include wiring for plenum spaces?
Absolutely. This unit comes standard with a 10ft plenum-rated cable, making it suitable for ceiling plenum installations and ensuring compliance with local building codes.

What is the default fail-safe position for this model?
The M322A01 is a normally closed actuator. In the event of a power failure, the internal spring return mechanism will automatically drive the valve to the closed position.
