Focus On : Valves, Actuators and Positioners

valves and actuators

Advances in control valves, valve actuators and positioners are changing the shape of industrial automation and control for plant engineers.

Examples include: a digital valve controller (electronic positioner) with automated diagnostics; and a wireless plug-in for accessing valve maintenance data even on plants running with older 4—20mA control systems. Then there are: new packings and seals, to reduce fugitive emissions; improved valve trims, for plant noise reduction and increased valve life; and valve controllers with contactless feedback, cutting out mechanical actuator linkages and, again, improving maintenance-free control valve life expectancy.

Plant Engineer's coverage of valves, actuators and positioners includes even a lowly butterfly valve now turned from shut off valve into rotary control valve with ball valve or globe valve performance.
