Series 9140 Linear actuators accept electrical line voltage signals from a switched output controller to position a final control element, such as a damper, control valve, louver, stoker lever, variable speed transmission, or any similar device, over a six-inch range of travel.
Optional features are available to suit any combustion control or process control application. These include adjustable starting position switches, an isolated auxiliary end-of-travel switch, weather-resistant housing, handwheel, and an externally or internally generated position feedback signal.
Cleveland Controls series 9140 Linear actuators require no mechanical brake assembly. The inherent braking-action of the synchronous stepping motor prevents overtravel without the wear and stress associated with friction or “DC” braking.
