Facilitates Economical Operation

The CMA (Compact Modulating Actuator) extends the scope of Rotork’s technologies and the benefits inherent in the Rotork CVA electric control valve actuator range by increasing the areas of flow control that can take advantage of these advanced features.

The Rotork CMA is available in linear, quarter-turn and multi- turn versions and a range of five compact sizes, facilitating the economical operation of numerous types of control valve, damper and pump stroke adjuster applications. Single-phase or DC electrical power supply is all that is required for control valve actuation, saving the on- going costs associated with the operation and maintenance of instrument air supplies.

The maintenance-free CMA drive train, permanently lubricated and protected in an IP67 watertight and, where required, explosion-proof enclosure, can be mounted in any orientation.
