The Rotork Skilmatic self-contained electro-hydraulic valve actuator range is suitable for safety-related applications including emergency shutdown (ESD) duty.

The range is claimed to combine the simplicity of electrical operation with the precision of hydraulic actuation and the reliability of mechanical failsafe motion.

The new control and monitoring system, added to the Skilmatic range, is based on the Rotork IQPro intelligent electric actuator technology.

The resultant Skilmatic SI/EH Pro range combines existing Skilmatic features with new text displays, performance monitoring and data logging that includes valve signature profiles.

The compact and robust actuators deliver a reliable means of valve management and positioning a valve to a safe condition.

Safe valve positioning is selectable for failsafe-to-open, failsafe-to-close or lock-in position on power failure or ESD signal.

The new SI/EH Pro control module enables simple, safe and swift non-intrusive commissioning, with infrared and Bluetooth control by means of an intrinsically safe handheld setting tool.

Settings including internal hydraulic pressure, position, limits, control, alarm and indication functions can be accessed and adjusted utilising user-friendly ‘point-and-shoot’ menus.

Actuator status, control and alarm icons are provided on the illuminated LCD display, which also enables 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.

Offering flexibility of customisation to suit the application, the actuators can be integrated into the majority of digital bus control systems, including Pakscan, Foundation Fieldbus, Devicenet, Profibus and Modbus.

Designed to SIL3 standards for use in safety-critical applications, the actuators are also capable of partial stroke testing, enabling isolating valves to be function tested without affecting the process – something of particular importance in ESD applications.

Further enhancements include preventative maintenance features such as local and remote fault detection.

These features are recognised as providing increased security for safety-related duties such as remotely operated shut-off valves (ROSoVs) – an area where the Skilmatic EH actuator is often specified.

All actuators are available with hazardous-area certification encompassing Atex, Inmetro, IEC, FM, CSA and GOST.

The double-sealed electric enclosure is watertight and dustproof in ratings up to IP68.

The Skilmatic SI/EH Pro range delivers rotary output torques from 65Nm to 600,000Nm and linear thrusts from 1.7kN to 5,500kN, making it suitable for valves of virtually any size and design.
