The ‘Q’ range is a single phase, electric actuator which is available in two versions, both with the Rotork ‘double sealed’ IP68 enclosure. The ‘Q’ standard version is suitable for simple open/close duties, where on/off control is required. This is achieved without the need for reversing contactors, giving simplified wiring. The design of the motor and limit switch mechanism, ensure combined ease of setting and reliability in use.
