Industrial AV400 Valve Linkage Assembly

AV-400 Valve Linkage Kit from Schneider Electric (Barber-Colman) is a field-installable assembly that couples the MK-2690 Proportional Pneumatic Valve Actuator to VB-7xxx and VB-9xxx valve bodies for precise proportional control of valves and dampers. The kit includes springs for multiple control signal ranges (3–7 psi, 5–10 psi, and 8–13 psi) and the hardware needed to attach the MK-2690 to the valve body; the actuator itself provides a nominal 1/2" stroke and supports up to 30 psi air supply with 1/8" FNPT connections located on the housing. Typical applications include HVAC and building automation where proportional valve or damper control is required, and the AV-400 is designed to be compatible with current and select older VB valve bodies.
