• Withstands vibration and shock at frequencies to 120 Hz and accelerations to 2G
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.
