Hagan Pneumatic Power Positioners have defined the standard of excellence in fan and damper actuation for more than 70 years.

These actuators convert the linear motion from a pneumatic piston into an 80° rotation of a drive arm. With few moving parts, the pneumatic power positioner remains the simplest, most reliable and most cost-effective method of actuation. Torque ranges are offered from 400 ft-lbs to 4,600 ft.-lbs.

The PowerVUE design uses the same rugged Hagan actuator and frame construction, combined with the accuracy and reliability of the Fisher FieldVUE DVC5000/6000 Digital Valve Controller.

The DVC5000 controller, using the HART or FOUNDATION fieldbus communications protocols, gives easy access to information that is critical to process operation.

The controller uses feedback from the actuator travel position to diagnose not only the instrument, but the actuator as well.

The information from the DVC5000/6000 can be integrated into control systems or be received for a single loop.

These instruments use two-wire loop power for low-cost replacement of existing instruments. The two-wire design avoids cost of separate power and signal wiring.

Self-diagnostic capabilities allow you to check fan/damper actuator performance in place. You can compare the present signature (load, friction, etc.) against stored signatures to discover performance changes before they cause problems.

Field maintenance of these instruments is easy. Repair consists of quick replacement of a single master module without disconnecting wires or tubing. Troubleshooting of the master module is fast and easy in the instrument shop.
