ABB气动执行器LP UP

The UP (Universal Pneumatic) and LP (Linear Pneumatic) actuators are designed to precisely position these final control elements based on the set point from the control system. UP and LP actuators are sized according to the required damper torque/force and travel speed. Options are available for achieving desired safety if the power or control signal fails, such as:

- move the damper to a safe position either fully open or

closed or

- hold the last valid damper position.

These options allow the boiler design engineer to select the appropriate safety control philosophy of the combustion loop.

The use of Digital Positioning Technology ensures accurate damper positioning as well as providing advanced diagnostics to provide the user with real time positioning data as well as predictive maintenance information for reliable damper control.
