ABB AV2 and AV27 Electro-Pneumatic Valve Positioners
The ABB AV2 Electo-pneumatic valve positioner accepts a 4-20ma input and signal
The basic unit can be provided with a gage block or a manifold (which also has connections for the gauges. A number of different drive shafts are available to match with different actuators..
The AV27 is a basic Electo-pneumatic positioner with an explosion proof and intrinsically safe I/P connected to it which makes it suitable for hazardous areas
The TZIDC Series provides additional capabilities in a intelligent positioner
