Schneider Electric (Barber Colman) M1500A-VB Actuator

Engineered for high-performance HVAC systems, the Schneider Electric (Barber Colman) M1500A-VB Actuator is a robust non-spring return (NSR) linear actuator delivering 337 lbf (1500 N) of force. This Forta series actuator is designed for precision modulation of Schneider Electric globe valves, including the VB-7000 and VB-8000 series, using a secure screw-mount interface. Operating on a 24V power supply, it supports versatile control signals including proportional 0-10Vdc, 2-10Vdc, and 4-20mA (with the included 500 Ohm resistor), as well as floating control for maximum field flexibility. The brushless DC motor ensures quiet, reliable operation with a maximum noise level of 32 dBa, while the 2-10Vdc technical feedback allows for real-time monitoring of valve position. A veteran technician will appreciate the easy "one-touch" calibration and DIP-switch selectable direct/reverse action, making this globe valve actuator a standard for demanding chilled water, hot water, and steam applications.

• Flexible Control Input: Field-selectable proportional and floating controls accommodate diverse controller outputs without requiring additional hardware.
• Direct Mount Integration: The screw-mount design eliminates the need for separate linkage kits when installing on VB-7xxx series valves, reducing labor time.
• Precision Performance: Delivers high-torque 337 lbf force with electronic valve sequencing and flow curve selection for optimized fluid dynamics.
• Diagnostic Feedback: Built-in 2-10Vdc feedback signal provides accurate positioning data to the building automation system for advanced troubleshooting.
• Manual Override: Features a high-visibility red handle for manual positioning during commissioning or maintenance procedures.

• Is the M1500A-VB compatible with steam valves? Yes, this actuator is rated for use in steam, chilled water, and hot water applications within specified temperature ranges.
• Does this actuator require a separate linkage kit? For VB-7xxx series globe valves, it screws directly onto the bonnet nut. For VB-8xxx or VB-9xxx valves, an AV-822 or AV-812 linkage kit may be required.
• Can I use a 4-20mA signal? Yes, the unit includes a 500 Ohm resistor specifically for 4-20mA proportional control applications.
