ROTORK electric actuator

ROTORK, as a manufacturer of actuators, has developed a highly reliable design with decades of experience in installation and use in various environments due to its durable products. And make the executing agency in a leading position in terms of operation and safety applications. ROTORK, a British company, launched the intelligent electric actuator (IQ series) in the 1990s, the world's first actuator - which allows you to debug and query without opening the electric box cover. Compared with ordinary actuators, it has the following characteristics:

(1) Convenient parameter remote control setting function. Before being put into use, the parameters can be remotely set by aligning the actuator with the dedicated setting tool provided by the manufacturer. Not only does it simplify the setting work procedures, but it also improves the safe operation of equipment, especially in places that require explosion protection, which is particularly important;
(2) Rich online display functions. By adopting LCD display technology and utilizing a built-in LCD display panel, not only can the valve's open and closed status and normal valve opening be accurately displayed, but important information can also be displayed in case of parameter settings or actuator malfunctions;
(3) Complete self diagnosis and protection functions. It can diagnose servo motor overload, overheating, and power status online, and automatically identify the phase of the three-phase power supply. In emergency situations, the actuator can maintain its position or run to a pre-set safe position;
(4) Advanced control functions. Adopting computer technology, advanced automatic following control technology is designed as one of its standard functions. The response speed of the actuator is proportional to the actual required deviation, which is known as "variable speed control",
Greatly improved the response quality of the actuator.

Performance of execution mechanism
Double sealed, double protected
The rated protection level of IQ casing is IP68- underwater 3 meters, 48 hours, NEMA4/4X/6。 It is completely waterproof, dustproof, and not breathable. The Rotork dual sealing system ensures that internal components are protected as they are isolated from the terminal box by waterproof wiring terminal modules. Even during on-site wiring, the protection is maintained by removing the terminal cover, and the terminal module is independently sealed.

Non invasive lifetime seal
IQ on-site debugging does not require removing the electrical box cover. All settings and adjustments are completed using the provided infrared setter. After assembly in the controlled environment of our manufacturing plant, gas exchange has been eliminated - all internal components are protected for life. Non invasive controller means that there is no through axis passing through the control box.
Simple and reliable, IQ simplifies design while expanding specifications and performance.

Torque measurement
The actuator can reliably and accurately measure the force acting on a valve, which is the basis for providing protection to the valve and actuator. IQ uses its patented output torque measurement system, which is developed from familiar process measurement techniques such as pressure sensors. This technology, which has been validated and tested in industry, is suitable for valve actuators. In the case of a load, using a pressure-sensitive resistor sensor installed inside the torque sensor, the reaction force of the motor worm thrust is directly converted into an electrical signal proportional to the output torque, which can obtain accurate and reproducible torque measurement values independent of frequency, voltage, and temperature changes.

Valve position measurement
Reliable process control depends on accurate positioning at the end of the valve stroke, while hydraulic control depends on accurate positioning in the middle of the valve stroke. The patented non-contact valve position measurement system is the simplest design in actuator control. The decomposer with only one movable component converts the rotation of the output center sleeve into an electrical signal, which is then compared with the limit stored in a secure and permanent memory.

Component reduction
Reasonable mechanical and electrical systems improve reliability. As the foundation of IQ, the improvement of the handwheel structure and control chassis has enhanced the reliability of the actuator. newest? quot; The technology of system integrated chips has been applied to IQ control modules. The number of components has significantly decreased, thereby reducing the complexity of interconnection, wiring, and printed circuit boards. Enhanced features such as data display and better system protection have been adopted to improve performance and reliability.

Security integrity
The initial development of IQ was aimed at improving the safety and integrity status of valve actuators. Through further design and innovation, Rotork is able to provide a solution that allows process engineers to select actuators based on the determined safety integrity level assessment. Given that international standards such as IEC615081, ISA-S84.01, and DIN19250 have become requirements for evaluating the safety and completeness of process systems, Rotork would be happy to discuss your requirements.
