Rotork Process Controls, at ACHEMA 2012, Hall 8.0, Stand A76., will be demonstrating the benefits of all-electric control valve actuation as represented by the proven and established CVA range and the recently introduced CMA (Compact Modulating Actuator).
A working demonstration unit on the stand compares CVA and CMA electric actuation with the traditional pneumatic approach to illustrate the operating advantages, reduced costs and user-friendly features that are enabled by all-electric control. The demonstration also highlights the hidden costs associated with pneumatic operation.
As well as eliminating the inherent running and maintenance costs demanded by an instrument air supply, Rotork CVA/CMA actuation technologies introduce maintenance-free operation, simple and intuitive set-up, internal position feedback and no recalibration requirement within a reduced overall valve package size and a fully sealed watertight enclosure. The advantages and economies provided by these rugged all-electric ‘fit-and-forget’ products have been proven in environments as diverse as power stations, oil refineries, food factories and mineral plants.
