Features:

The APEX 8000 High-performance positioners feature a unique two-stage stage pneumatic relay that provides un-rivaled performance. This two-stage relay allows end users exceptional control traditionally found only in digital positioners.

The APEX 8000 line also utilizes a modular design that allows maximum flexibility for the end user. The high visibility UltraDome Indicator allows plant personnel to quickly and easily identify valve status. Multiple current-to-pressure (I-P) options are available to convert the APEX pneumatic positioner into a 4-20mA electro-pneumatic positioner. The I-P's are available as a stand alone item and are globally certified for hazardous locations applications as well as weatherproof and intrinsically safe installations.

The Apex 8000 positioners are easily calibrated with minimal tools required and provide years of accurate, reliable service. The non-interactive zero and span calibration permits quick and easy calibration. A unique gain adjustment allows the user to better match the postioner to actuator dynamics. Multiple cam options allow the user to select from a wide range of positioning characteristics: standard 3-15 psi, split ranging, 180° direct and reverse acting are easily accomplished with the standard cam configuration. Other options are available upon request.

In addition, the APEX 8000 allows options for transmitters and end of travel limit switches to be mounted internally. (General purpose and Division 2 applications only). For Division 1 applications, the APEX 8000 is available with a top-mounted UltraSwitch option for discrete or analog feedback.
