Schneider Electric (Barber Colman) AV-430 Linkage Els PW 17895 or differential air pressure inThe Schneider Electric (Barber Colman) AV 430 Linkage is a heavy duty mechanical interface designed for field assembly of pneumatic valve actuators to globe valve bodies. Built with a die cast aluminum mounting bracket, this kit provides the structural rigidity required for reliable HVAC control valve modulation. It is specifically engineered to bridge MK 66X1, MK 68X1, and MK 6911 actuators with two way and three way valve bodies ranging from 1 2" to
