All Electric Modulating Actuators

Rotork has announced its new CMA series of all electric modulating actuators suitably sized for linear, quarter-turn and rotary operation of pump, damper and control-valve applications requiring precise position control and continuous modulation.

CMA actuators are powered by single-phase or direct current supplies, eliminating the need for air hoses and compressors used with similar pneumatic control-valve actuators. Set-up and configuration is easy via push-buttons and an internal six-segment LCD display.

Resolution is 0.20% on linear and quarter-turn applications and 2 degrees on the multi-turn configuration.

Other features include a permanently lubricated and maintenance-free drive train; a 4-to-20 mA loop-powered feedback signal; and digital communication options including HART®, Foundation FieldbusTM, Profibus®, Modbus®,  Rotork’s PakscanTM and RIRO for discrete hardwired control.

The new CMA actuators complement Rotork’s CVA electric control-valve actuators, which were introduced in 2008 and are operating in thousands of process control applications throughout the world.
