The Schneider Electric (Barber Colman) M1500A-VB is a heavy-duty Forta series globe valve actuator engineered for precise control in commercial and industrial HVAC hydronic systems. Operating on a 24V power supply, this actuator supports both floating and proportional control modes, making it a versatile solution for a wide range of building automation and valve control applications.
Control Signal Flexibility
The M1500A-VB accepts multiple input signal types to integrate seamlessly with virtually any building automation or DDC control system:
- 0 to 10 Vdc control signal
- 2 to 10 Vdc control signal
- 4 to 20 mA control signal (requires 500 Ohm resistor, included)
- 2 to 10 Vdc feedback signal for accurate position monitoring
