General Purpose

Rotork Skilmatic Model 301/2 general purpose, two position, quarter turn actuators, offer the simplest solution to spring return, fail-safe electric actuation. Operating from a standard 230/110V AC supply, the actuators are designed for general application with ball, butterfly valve and fire damper. The actuator utilises the fully sealed SKIL electro-hydraulic power system with internal spring return action for clockwise or anticlockwise rotation. Housed in a weatherproof enclosure, the actuators provide a torque range of 24NM (212 in lbs), to 510NM (4513 in lbs).

Optional Asi field bus, manual override gearbox and thermal jacket is available.

Industrial Weatherproof

Rotork Skilmatic model 405/6/7 quarter turn actuators, are specifically designed for modulating control application. Accepting a standard 4-20mA or pulsed signal to position a valve or damper, to a resolution better than 0.2 of a degree and offering 100% duty rating. The units are also ideal for two position and emergency shutdown applications, where fail-safe, spring return action is required. The actuators are housed in a compact and robust weatherproof enclosure to IP65/NEMA4X to suit all industries and remote valve locations with torque ranges from 24NM (212 in lbs) to 510NM (4513 in lbs).

Flameproof

Rotork Skilmatic model 413QT flameproof quarter turn actuators, are designed for both modulating and two-position, fail-safe electrical actuation, in Zone 1 hazardous areas.

Certified to E.Exdme IIB T3 and Class 1, Zone 1, AExmd IIB T3.

The actuators are ideal for use with all ball, plug, butterfly and control valves, with torque range from 52NM (460 in lbs) to 510NM (4513 in lbs).

The model 413QT is available with internal 4-20mA positioner and fail-safe quick closure ESD options.
