Schneider Electric (Barber Colman) AV-396 Valve Linkage

The Schneider Electric AV-396 is a professional-grade Barber Colman valve linkage kit engineered for high-torque applications requiring precise fluid control. This heavy-duty linkage is purpose-built to interface gear train actuators—specifically the MA, MP, and MC-5 series—with large-bore VB-9xxx series valves ranging from 2-1/2" to 4" nominal pipe size. Featuring a robust 300 lb stem force capacity, the AV-396 ensures reliable seating and tight shut-off even in high-differential pressure systems. For technicians retrofitting older pneumatic systems or maintaining existing hydronic loops, this complete linkage kit provides the necessary mounting brackets and stem extensions to convert rotary actuator motion into linear valve travel. Its construction is designed to withstand the thermal stresses found in commercial HVAC boiler and chiller plants, maintaining alignment and calibration over extended duty cycles without the frequent need for field adjustments. This makes it a critical component for Schneider Electric valve actuator repair and building automation upgrades.

• Universal Compatibility: Seamlessly adapts gear train actuators to 2-1/2" through 4" VB-9213, VB-9223, and VB-9313 series valve bodies.
• High Force Rating: Rated for a maximum of 300 lbs of stem force, providing enough torque for larger globe valves in high-demand environments.
• Industrial Durability: Machined steel and cast components prevent linkage flex, ensuring accurate stem positioning and optimized flow control.
• Streamlined Installation: Comprehensive kit includes all hardware required to mount Schneider Electric actuators to Barber Colman valve assemblies.

Common Questions

What actuators are compatible with the AV-396 linkage?
This linkage is specifically designed for use with Schneider Electric (formerly Barber Colman) MA-521x, MP-521x, and MC-521x series gear train actuators.

Can I use this linkage on valves smaller than 2-1/2"?
No, the AV-396 is dimensioned specifically for the larger 2-1/2" to 4" VB-9xxx series valves. Smaller valve bodies require the AV-393 or similar low-force linkages.

Does this kit include the actuator itself?
The AV-396 is a hardware linkage kit only. The actuator and valve body must be sourced separately based on your specific torque and flow requirements.
