Schneider Electric (Barber Colman) AV-821 Adapter Kit

The Schneider Electric (Barber Colman) AV-821 Adapter Kit is an essential field component for technicians needing to interface Forta M400, M800, M900, and M1500 U-bolt style actuators with VB-7xxx series valves. This high-precision valve linkage kit ensures a secure and properly aligned mechanical connection, facilitating accurate stem positioning and reliable flow control in chilled water, hot water, and steam applications. Designed specifically for 1/2-inch to 2-inch globe valves, the AV-821 simplifies the retrofit or repair process by providing a standardized mounting platform for non-spring return and spring return linear actuators. By utilizing this Schneider Electric actuator adapter, contractors can maintain system integrity without replacing entire valve bodies, ensuring peak performance of internal plug and stem assemblies. This kit includes the necessary jam nut, stem adapter, and bonnet adapter required for a robust installation on VB-7000 series hardware.

• Universal Compatibility: Enables seamless integration of Forta U-bolt actuators with standard VB-7xxx series bronze globe valves.
• Refined Installation: Includes fundamental hardware such as stem and bonnet adapters to eliminate field fabrication and ensure precise stroke alignment.
• Industrial Durability: Optimized for high-demand HVACR environments, supporting both two-way and three-way valve configurations.
• Cost-Effective Retrofitting: Allows for the upgrade of older Barber Colman or Schneider Electric linkages to modern Forta actuator technology.

• Which actuators are compatible with the AV-821? This kit is specifically for Forta M400, M800, M900, and M1500 actuators that utilize the U-bolt mounting style.
• Does this kit work for all VB-7xxx valves? Yes, it is designed for 1/2" through 2" VB-7xxx series valves to facilitate professional-grade actuator mounting.
• Are tools required for installation? Reliable installation typically requires a 5/16" wrench (or TOOL-20-1), a 7/16" wrench, and an M-370 wrench for the valve nut.
