The new actuator is available for the direct-drive actuation of linear or quarter-turn control valves and demonstrates highly accurate control valve automation, advanced, non-intrusive calibration and valve diagnostics.
The CVA is engineered to deliver high precision valve positioning and facilitate the tightest possible tolerances on the process variable, enabling process quality and output to be optimised. On loss of mains power, built-in super-capacitors allow the CVA to move the valve to a desired position, programmable as open, close, any intermediate position or stay-put. Manual operation is also optionally available.
