Schneider Electric (Barber Colman) AV-607-1 Valve Linkage

The Schneider Electric AV-607-1 Valve Linkage is a heavy-duty hardware assembly engineered to bridge DuraDrive linear actuators with large-bore globe valves. As the direct AV-607 replacement, this kit provides the necessary mechanical interface for VB-8xxx series valve bodies (2-1/2" to 5") and VB-931x series valves (1-1/2" to 4"). It is also backward compatible with discontinued 1-1/2" to 4" VB-92xx series linkages, making it essential for retrofitting legacy hydronic systems. The design supports both single and dual actuator configurations to meet specific torque and close-off pressure requirements in commercial HVAC applications. By ensuring precise stem positioning and stroke travel, the AV-607-1 linkage kit maintains optimal flow control and sealing integrity. Field installation is streamlined via a robust mounting bracket and stem extension components, specifically calibrated for globe valve actuator mounting in high-capacity chilled water or steam service.

• Compatible with 2-1/2 to 5 inch globe valves including VB-8213, VB-8223, and VB-8303 models.
• Facilitates dual actuator mounting for high-torque applications requiring increased close-off ratings.
• Directly replaces legacy Barber Colman AV-607 hardware without requiring piping modifications.
• Rugged construction withstands high ambient temperatures common in mechanical rooms and steam stations.
• Precise mechanical stroke adjustment ensures full seat engagement and reduces hunting in proportional control systems.

How do I install the AV-607-1 on a legacy VB-92xx valve?
The AV-607-1 includes the necessary stem extensions and mounting plates to adapt modern DuraDrive actuators to the older 1-1/2" to 4" VB-92xx bodies. Ensure the valve stem is fully retracted during the linkage calibration to prevent internal seat damage.

Can this linkage be used for dual-mount actuator setups?
Yes, the AV-607-1 is specifically designed to support dual MX41-6xxx or MX40-7xxx series actuators when the valve size or system pressure exceed the capacity of a single drive unit.

What is the difference between AV-607 and AV-607-1?
The AV-607-1 is the updated manufacturer revision. It features improved metallurgical tolerances and updated mounting hardware to better accommodate the current generation of Schneider Electric linear actuators while maintaining the same physical footprint.
