Electro-Pneumatic Positioner – Type AV3

The Type AV3 positioner is an electro-pneumatic control device that satisfies a wide range of applications. It provides fast, sensitive and accurate positioning of pneumatic single or double acting actuators. The Type AV3 positioner accepts a 4-20 mA current that is applied to an I/P converter to generate an internal signal pressure. If a loss of signal occurs the positioners retain their position just prior to the signal loss. This strategy is ideal for process applications such as with fuel, cooling water and fan dampers where interruptions are unacceptable. The Type AV3 positioner can be equipped with either an optional potentiometric or a 4-20 mA position transmitter.
