Schneider Electric (Barber Colman) M800A-VB Actuator

The Schneider Electric M800A-VB is a versatile Forta Globe Valve Actuator designed for precise control in HVAC hydronic systems. This 24V globe valve actuator supports multiple control signals, including floating or proportional control, and is field-configurable for 0 to 10Vdc, 2 to 10Vdc, or 4 to 20mA (utilizing a 500 Ohm resistor) inputs. Optimized for demanding commercial applications, it delivers a consistent 180 lbf (800 N) of force to ensure positive shut-off and modulating accuracy. The unit features built-in 2 to 10Vdc feedback for real-time positioning data and simplifies installation with a secure screw mount design to the valve linkage. Engineered for durability, the M800A-VB linear actuator is compatible with a wide range of Schneider Electric (formerly Barber Colman) VG7000 and VB-series valve bodies, making it a reliable choice for retrofits and new installations requiring high-precision fluid regulation.

• Universal Signal Compatibility: Supports various BAS control signals including 4-20mA and 0-10Vdc for seamless integration.
• High Torque Performance: Provides 180 lbf of linear force to handle high differential pressures in globe valve applications.
• Easy Commissioning: Features self-calibrating stroke and a built-in feedback signal for accurate AEO-optimized performance monitoring.
• Durable Construction: Built for industrial use with a robust drive mechanism for long-term HVAC valve automation.

How do I change the control signal on the M800A-VB?
The input signal is configured via internal DIP switches, allowing you to toggle between floating and proportional modes or adjust the input voltage/current range.

Is this actuator suitable for steam applications?
Yes, when paired with the appropriate high-temperature valve linkage, the 180 lbf rating is sufficient for many low-to-medium pressure steam setups.

What valves are compatible with the screw mount design?
The M800A-VB is primarily designed for Schneider Electric Forta and Barber Colman VB-series globe valves using the standard screw coupling.
