Schneider Electric (Barber Colman) AV-495 Linkage Kit

The Schneider Electric AV-495 Linkage Kit is a field-installable hardware solution engineered for high-performance coupling of pneumatic actuators to large-scale globe valves. Designed for heavy-duty HVACR applications, this Barber Colman AV-495 kit allows for the precise integration of MK-68X1, MS-8XX1X-XXX, MSR-8801X, MSR-8601X, and MSR-8701X series actuators. It is specifically optimized for use with Schneider Electric VB-9213, VB-9223, and VB-9313 valve bodies with port sizes ranging from 2-1/2" to 4".

For technicians managing pneumatic actuator linkage replacements, the AV-495 ensures reliable stroke transfer and maintains strict close-off pressure ratings across the full range of VB-9000 series valve assemblies. This kit is a critical component for maintaining assembly integrity in steam and water systems, providing the necessary mechanical advantage for 50-square-inch actuators to drive flanged valve plugs efficiently. Whether you are performing a field retrofit or a new installation, this valve repair part provides the exact tolerances required for ANSI Class IV leakage standards and long-term operational stability in commercial environments.

• Broad Compatibility: Seamlessly hooks up MK-6800 and MSR-8000 series pneumatic actuators to large-bore VB-9000 flanged valves.
• Engineered Precision: Maintains accurate stem alignment and stroke timing to prevent premature packing wear and hunting.
• Field-Ready Design: Simplifies the retrofitting process for existing valves without requiring full system teardowns.
• High Torque Support: Robust construction handles the force requirements of 2-1/2" to 4" valves in high-differential pressure applications.

Which valve bodies work with the AV-495?
This kit is designed for 2-1/2" to 4" flanged globe valves, specifically the VB-9213 (2-way normally open), VB-9223 (2-way normally closed), and VB-9313 (3-way mixing) models.

Can I use this for electric actuators?
While originally pioneered for pneumatic lines like the MK-68X1, this kit is frequently used to adapt specific Schneider Electric gear-train and hydraulic-style actuators; always verify your specific actuator's bolt pattern and stroke length.

Does it include the stem extension?
Yes, the AV-495 includes the necessary linkage components and stem extensions required to bridge the gap between the actuator piston and the valve stem.
