Rotork CVA modulating electric actuator (CVL linear / CVQ part-turn), Class D, IP68

Rotork CVA is a precision electric actuator for continuous modulation of most control valve types and sizes. Continuous modulation per S9 (IEC 60034) and Class D (ISO 22153), IP68, NEMA 4 and 6 enclosure, explosion-proof versions.

CVL is the linear output version with thrust of approx. 890–22,241 N (200–5,000 lbf). CVQ is the part-turn version with torque of approx. 22–271 Nm (480–2,400 lbf·in). Low power consumption makes the range suitable for remote solar-powered sites.

Control: analog, discrete, Pakscan, HART, Profibus, Foundation Fieldbus, Modbus networks; hardwired and intrinsically safe I/O options. Non-intrusive Bluetooth calibration, built-in datalogger for predictive maintenance, optional handwheel.
