Pneumatic Positioner Type AV1
DESCRIPTION The Type AV1 positioner is a control device that satisfies a wide range of applications. It provides fast, sensitive and accurate positioning of pneumatic single or double acting actuators. The AV1 receives an external pneumatic signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator. If a loss of signal occurs, the positioner goes to the 3 psi position. Type AV1 positioners can be equipped with either an optional potentiometric or a 4-20 mA position transmitter.
FEATURES
• Withstands vibration and shock at frequencies to 120 Hz and accelerations to 2G • Low air consumption
• Can control both single and double-acting, linear and rotary type actuators • Split range capability allows sequencing of multiple actuators using a single control signal • Simplified reverse operation
• Continuously adjustable span and zero for each stroke level • Adjustable speed control of actuator without additional hardware
• Standard model has high delivery capacity and Performance Series increases speed of response even more • Vent design allows natural gas operation • NEMA 4X version available • Optional manifold assembly
• Large array of accessories available to customize for specific applications
