ABB AV1 and AV27 Pneumatic Valve Positioners
The ABB AV1 pneumatic valve positioner accepts a 3-15 psi or 3-27 psi pneumatic input and since it doesn't need electricity can be used in an hazardous area.
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..
For a 4-20 ma input please see the other models in the AV Series or the ABB Intelligent positioners, the TZIDC Series.
