Product description
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.
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.
Applications
Fan/Damper actuation for:
n Utilities
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.
n Steel mills
n Refineries
n Pulp and paper
n Wastewater (aeration blowers)

Theory of operation
Product Data Sheet
PDS 102-222.A01
Traditional positioners use a mechanical force/balance concept, whereby a pneumatic input signal forces a diaphragm down, actuating a valve which ports air into one side of a piston and vents the other side. A feedback spring provides a counterbalancing force as the actuator approaches setpoint.
Mechanical positioners have worked well for many years, but are subject to sticking as mechanical components become soiled, resulting in a situation where the actuator “hunts” for the proper position. The process variable is always above or below setpoint, providing poor control that costs significant money and causes excessive wear on the actuator/linkage/ dampers system.
The FieldVUE DVC5000/6000 Digital Valve Controller directly receives a 4-20 mA or fieldbus input signal. An independent feedback transducer provides an actuator position input, ensuring that the PowerVUE drive always moves to the setpoint demanded by the control system. Fieldbus versions of the DVC5000/6000 also offer PID loop control capability.
Options
Air Lock - mechanically locks the drive in place upon the loss of
plant air.
Valvelink advanced diagnostics
In addition to the standard features, advanced diagnos­tic features provide additional capabilities to diagnose problems with the DVC5000, the actuator, and even in the damper/ linkage systems. Actuator can be tested as it is put into service, and this data compared to an “as found” condition after years in service. Maintenance can be scheduled based upon actual need vs. traditional “time in service” criteria.
Manual Operator - handwheel/lever arm permits manual adjustment of drive.
Limit Switches - proof of position for purge/lightoff conditions may be accomplished by traditional mechanical microswitches.
Electric Position Transmitter - provides a 4-20 mA feedback signal representing actuator position. (HART versions only.)
Digital communications
4-20mA HART versions:
All operator information for setup and diagnostics is transmit­ted digitally via HART communications. A Rosemount 375 Hand-held or similar communicator may be used or a laptop computer with ValveLink Software. Emerson’s AMS offers the ValveLink software as an optional “snap-on” application. Instruments may be accessed individually or multiplexed through an “interchange” unit, providing continuous access to any number of Emerson’s instruments.
FOUNDATION fieldbus versions:
All operator interface is via the host computer console.
A hand-held device is available.

Performance Curves
Typical
arrangement
Set of characteristic curves for a typical air-operated power cylinder. Piston displacement and time are plotted for suddenly applied full-range positioning inputs to the cylinder. The linear sections of the curves correspond to steady speed.
Note: Stall torques are specified for all models. Emerson recommends that a 60% factor be applied to ensure fast control response. Rosemount Analytical power positioners are not recommended for reversing loads or heavy mass loads.
