Skilmatic SI Range
Rotork has introduced the next generation of SI actuators. The new SI range includes quarter-turn actuators with torque output from 75 to 200,000Nm and linear actuators with thrust output up to 400kN.
The SI range has been specifically designed to meet today’s control and safety needs for both two-position and positioning control applications. The actuators are offered with a wide range of operating speeds, emergency shutdown (ESD), inputs, partial stroke testing, analogue, HART and fieldbus communication capabilities to comply with all control configurations.
Designed primarily for fail-safe applications where functional safety is paramount, actuators within the range can be configured to fail-safe in three ways; loss of ESD signal and/or power supply. Loss of ESD signal only and loss of power supply only. The actuators are suitable for use in Safety Instrumented Systems (SIS).
