Rotork electric actuator ROTORK 

 U.S. Rotork (ROTORK) launched the company in the 90's intelligent electric actuator (IQ range), compared with the ordinary actuator has the following characteristics: 
 (1) to facilitate remote parameter setting function. Into use, just use the configuration tools provided by the manufacturer-specific, aimed at the implementation of the remote control device parameters can be set. Not only simplifies the set procedures, but also improve the safe operation of equipment, especially those requiring proof of the place is particularly important; 

 (2) extensive online display. Liquid crystal display technology, the use of built-in liquid crystal display panels, not only can accurately show the valve opening and closing state and the normal valve opening, etc., and in the parameter settings or actuator is faulty, they can show important information; 

 (3) improve the self-diagnosis and protection. It can be diagnosed online servo motor overload, overheating and power of the state, and can automatically identify the three-phase power supply phase, emergency situations, the actuator can be run to secure his position, or the safety of pre-set position; 

 (4) advanced control features. Use of computer technology, the advanced control technology automatically follow a standard design for its function. Actuator response speed and proportional to the size deviation of the actual requirements, the so-called "speed control", greatly improving the quality of the actuator response; 

 (5) strong on-site adaptability. Machine design with IP54 class protection, and the actuator port internal and external signals are also photoelectric isolation technology, improved reliability, especially in the implementation of components inside the control card using a shock fixation, with all the connectors are the "Flip" to prevent loosening, building-block structure makes maintenance very convenient.
