Schneider Electric (Barber Colman) M323A01 Actuator

The Schneider Electric (Barber Colman) M323A01 Actuator is a direct replacement for the legacy M123A01 model, offering a modernized solution for VBB/VBS Series ball valves. This 24V proportional spring return actuator is engineered for high-accuracy plant room control, featuring a plenum-rated 10-foot cable and a Normally Closed (N.C.) fail-safe position. As part of the SmartX lineup, it integrates a robust gear train with a 50% increase in face width on critical gears and stainless steel bearings to ensure long-term reliability in demanding HVACR environments.

Field configuration is handled through an accessible DIP switch panel, allowing technicians to select between 0-10 VDC, 2-10 VDC, 0-5 VDC, and 4-20 mA control signals without removing the housing. Designed for 1/2" and 3/4" bodies, the M323A01 utilizes a tool-less pop-top connection for rapid installation. Its 300:1 rangeability and split capacitor synchronous motor provides precise positioning for VAV reheat, fan coil units, and chilled water applications.

• Universal Control Input: Integrated DIP switches allow for seamless selection of proportional control signals (0-10V, 4-20mA) in the field.
• Direct Compatibility: Engineered as a drop-in SmartX actuator replacement for the discontinued M123A01 series.
• Enhanced Durability: Upgraded PCBA and reinforced internal gearing provide higher resistance to mechanical wear and electrical noise.
• Fail-Safe Protection: Reliable mechanical spring return ensures the valve drives to a Normally Closed position during a power loss.
• Efficient Installation: Features plenum-rated wiring and a linkage-free manual override for simplified commissioning.

• Is this compatible with older Barber Colman valve bodies? Yes, the M323A01 is designed to fit standard VBB and VBS series valves, which were previously paired with the M1 series.
• Does this require a separate linkage kit? No, this direct-coupled actuator features a tool-less mounting system that snaps directly onto the valve stem.
• Can the spring return direction be changed? This specific model is factory-set to Normally Closed; ensure your application requirements align with the fail-safe close orientation.
