Schneider Electric (Barber Colman) AV-813 Stem Adapter

The Schneider Electric (Barber Colman) AV-813 Stem Adapter is a critical hardware component designed for the specialized task of adapting actuator linkages to valve stems. For veteran technicians managing retrofits or repairs, the AV-813 facilitates the connection between 3/8-24 stem threads and 1/2-20 actuator threads. This heavy-duty threaded stem adapter is engineered for high-performance HVACR control environments, ensuring a precise mechanical union that eliminates play and maintains calibration accuracy during cycling. By utilizing the AV-813 adapter kit, you can effectively integrate Barber Colman globe valves with modern Forta or SmartX actuators, extending the service life of existing mechanical plants. Its robust construction resists the mechanical fatigue common in high-torque commercial applications, providing a secure actuator linkage connection that prevents slippage. When executing field replacements, this HVAC valve linkage adapter is essential for maintaining proper valve stroke and seating force, ensuring reliable flow modulation across your automation system.

• Ensures seamless conversion for 3/8-inch stem valves to standard 1/2-20 actuator threads.
• Constructed from high-grade, durable materials to withstand high-cycle actuator linkage stress.
• Facilitates Barber Colman valve compatibility with a wide range of current-generation electronic actuators.
• Maintains mechanical integrity under pressure, preventing stem blowouts when used as specified.
• Direct OEM replacement part ensures exact dimensional tolerances for a professional-grade fit.

• What specific thread sizes does the AV-813 adapt? It adapts 3/8-inch-24 valve stems to 1/2-inch-20 actuator stem threads.
• Is the AV-813 compatible with VB-7xxx or VB-9xxx valves? Yes, it is frequently used to adapt older Barber Colman 3/8" stems for use with modern linkage kits such as the AV-822.
• Are there specific tools required for installation? A standard 5/8-inch and 3/4-inch wrench are typically required to secure the adapter to the stem and jam nut.
