The Rotork Skilmatic self-contained electro-hydraulic valve actuator range combines the simplicity of electrical operation with the precision of hydraulic actuation and the reliability of mechanical failsafe motion for safety related applications including emergency shutdown (ESD) duty. A new, highly advanced control and monitoring system has been introduced, based on the proven Rotork IQPro intelligent electric actuator technology. The new SI/EH Pro control module facilitates simple and swift non-intrusive commissioning with infra-red and Bluetooth™ control by means of an intrinsically safe hand held setting tool. Settings including internal hydraulic pressure, position, limits, control, alarm and indication functions can be accessed and adjusted using user-friendly Rotork ‘point and shoot’ menus. Actuator status, control and alarm icons are provided on the illuminated LCD display which also gives access to real-time information such as pressure, diagnostics and help screens. Data from the actuator can be transferred to a PC for storage and analysis by means of Rotork’s free Insight II software. Designed to SIL3 standards for use on safety critical applications, the actuators are also capable of partial stroke testing, enabling isolating valves to be function tested without affecting the process. Further enhancements include preventative maintenance features including local and remote fault detection. These features are recognised as providing increased security for safety related duties such as ROSoV. All actuators are available with hazardous area certification encompassing ATEX, INMETRO, IEC, FM, CSA and GOST.
