The SI range of actuators from Rotork combine the simplicity of electrical operation with the precision of hydraulic control and the reliability of mechanical spring-return fail-safe action. Typical applications for Skilmatic SI actuators include functional safety-related Emergency Shutdown (ESD) inputs and Remotely Operated Shutoff Valve (ROSoV) duties. The new actuator uses a rack and pinion drive for a torque output of up to 1,000 Nm (737 lbf.ft).
Robustly constructed for challenging environments, SI actuators deliver a highly reliable means of safety valve positioning and intelligent management. With a wide choice of operating speeds, ESD options with single or dual inputs and partial stroke testing (PST) to meet a wide range of applications. All actuators are available with hazardous area certification and are suitable for use in SIL 2/3 systems.
Data logging of up to 3000 events
The actuators share the same intelligent features as Rotork’s IQ3 range, including non-intrusive commissioning by means of an intrinsically safe handheld Bluetooth wireless setting tool, performance monitoring and configurable data logging, increased functionality, and enhanced availability of valve and process data for asset management and data analysis.
The actuator data logger is capable of storing up to 3,000 events. Users can export data logs to Insight 2 or Rotork’s cloud-based Intelligent Asset Management (iAM) system. iAM enables proactive maintenance to help reduce unplanned downtime through advanced analytics of valves/flow control assets and anomaly detection. With Insight 2 software, users can review, configure and analyse actuator setup configuration and data logger information easily and quickly.
