Solid State/Pulse Input Positioner – Type AV4

The Type AV4 positioner provides fast, sensitive and accurate positioning of pneumatic single or double acting actuators. It responds to a solid state (DDC) or contact closure input (pulse) from a control device and converts the signal to a pneumatic signal. This pneumatic signal is converted to a pneumatic output, producing a motive force that positions the actuator. If a loss of signal occurs the positioners retain their position just prior to the signal loss. Designed to meet the special requirements of interfacing with state-of-the-art computer and microprocessor-based control systems, the AV4 utilizes an advanced pneumatic motor-to-pneumatic signal converter. In one compact package, it replaces three separate components: a motor-to-motor pneumatic converter, a pneumatic positioner, and a position transmitter.
