Double seal, double protection
The IQ enclosure is rated IP68 - 3 meters underwater, 48 hours, NEMA 4/4X/6. It is completely waterproof and dustproof, and not "breathable". The Rotork double sealing system ensures that the internal components are protected as they are isolated from the terminal box by the waterproof terminal block. Even when the terminal cover is removed during field wiring, protection is maintained and the terminal block is individually sealed.
Non-invasive lifetime seal
On-site commissioning of the IQ does not require removing the electrical box end caps. All settings and adjustments are done using the provided infrared setter. After assembly in a controlled environment in our manufacturing facility, gas exchange has been excluded - all internal components are protected for life. Non-intrusive controls mean there are no through shafts through the control box.
Simple and reliable, IQ simplifies design while expanding specification and performance.
Torque measurement
Actuators can reliably and accurately measure the force to operate a valve, which is the basis for valve and actuator protection. IQ uses its patented output torque measurement system developed from familiar process measurement technologies like pressure transducers. This technology, proven and tested in the industry, is suitable for valve actuators. In the case of load, using the piezoresistor sensor installed in the torque sensor, the reaction force of the motor worm thrust is directly converted into an electrical signal proportional to the output torque, and accurate and repeatable torque measurement values can be obtained, and Independent of frequency, voltage and temperature changes.
Valve position measurement
Reliable process control depends on accurate positioning at the end of valve travel, while hydraulic control depends on accurate positioning in the middle of valve travel. The patented non-contact valve position measurement system is the simplest design in actuator control. The one-page moving parts resolver converts the rotation of the output center sleeve into an electrical signal, which is then compared to limit positions stored in secure, permanent memory.
component reduction
Reasonable mechanical and electrical systems improve reliability. Improvements in the handwheel structure and control chassis, which are the basis of IQ, increase the reliability of the actuator. The component count is significantly reduced, reducing interconnect, routing and printed circuit board complexity. Enhancements such as data display capabilities and better system protection have been incorporated to improve performance and reliability.
