Rotork fluid power actuator Skilmatic range of actuators 


The Skilmatic range of actuators offer a unique and reliable solution for electric fail-safe and modulating control for both quarter-turn and linear valves and dampers.

They combine the simplicity of electrical operation with the precision of hydraulic control and the reliability of mechanical spring return or accumulator fail-safe action.

Available in both quarter-turn (65 to 600,000 Nm) and linear (1.5 to 3,850 kN) execution, the actuators are offered with a wide range of operating speeds, ESD inputs, partial stroke testing, analogue, Hart and fieldbus communication capabilities to comply with all control configurations. Independent limit switches and position feedback are provided. Selectable status and alarm indication with volt free relay outputs are also offered as standard.
