Rotork third generation Skilmatic delivers Smarter Failsafe Actuation

Rotork- Failsafe Actuator.jpgThe Rotork Skilmatic SI self-contained electro-hydraulic valve actuator combines all-electric simplicity with the precision of hydraulic actuation and the reliability of mechanical failsafe operation. Typical applications for Skilmatic actuators include functional safety related Emergency Shutdown (ESD) and Remotely Operated Shutoff Valve (ROSoV) duties.

Skilmatic’s advanced control and monitoring system has now been further developed with the introduction of the 3rd Generation, incorporating proven Rotork IQ3 intelligent electric actuator technology. Communication and data logging capabilities have been increased in response to end users’ desire to access more valve related data, both in the field and in the control room.

The 3rd Generation of the SI actuator will consist of four models with multiple actuator sizes known as SI³-1, SI³-2, SI³-3 and SI³-4, enabling Rotork to offer quarter-turn failsafe actuation from 65Nm up to 600,000Nm for functional safety applications. As part of the development Rotork has enhanced the range by introducing the new SI³-3 standard range of spring return actuators with a torque range of 2,000Nm to 20,000Nm. This new range offers a wide choice of operating speeds, additional ESD options with single or dual inputs and enhancements to partial stroking to meet a wide range of applications.

Skilmatic SI 3rd Generation actuators combine established features including non-intrusive setting, performance monitoring and configurable data logging with an extended torque output range, increased functionality and enhanced availability of valve and process data for asset management and data analysis, displayed in a new, large and information-rich format.

Robustly constructed for challenging environments, SI 3rd Generation actuators deliver a highly 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 either loss of power or a range of programmable ESD signal options.

The SI 3rd Generation control module facilitates simple, safe and swift non-intrusive commissioning by means of an intrinsically safe hand held setting tool with infra-red and Bluetooth™ interfaces. 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 an advanced new dual-stack toughened glass illuminated display which also gives access to real-time information such as pressure, diagnostics and help screens.
