New features added to this family of electric actuators
This company has added several new features to its line of CMA electric actuators (photo), including increased functionality for manual local control at the valve, enhanced LCD positional display and programmable fail-to-position performance. CMA actuators are available for quarter-turn, rotary or linear operation and are used in many applications, including for the operation of process-control valves and other continuous modulation applications, such as for metering pumps and damper drives. The actuators are powered by single-phase or direct-current supplies, and include a permanently lubricated and maintenance-free drive train. Hall 8.0, Stand A76 — Rotork Controls GmbH, Hilden, Germany
