Schneider Electric (Barber Colman) AV-497 Linkage Freon SPST Contact Arrangement: Simplifies wiringThe Schneider Electric (Barber Colman) AV 497 is a critical pneumatic actuator linkage kit designed for seamless field assembly of MK 6811 and MK 6911 actuators onto large scale valve bodies. This robust mechanical interface allows for the precise conversion of pneumatic signals into linear force, specifically coupling the MK 6811 actuator to VB 8xxx series valves in the 2 1 2" to 5" size range. For larger 6" applications, this kit facilitates the
