Skilmatic

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 600000 Nm) and linear (1.5 to 3850 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 the control configurations. The Independent limit switches and position feedback are provided. The Selectable status and alarm indication with the volt free relay outputs are also offered as standard.
