The Rotork IQ3 actuator's dual-stacked display has a toughened glass screen that provides a quick visual readout of real-time operational data. The user interface has configurable datalogger functionality, it can be programmed with a handheld Bluetooth® remote, and also available for the IQ3 is the InSight2 PC software. Please watch the short IQ3 display video to see some of the user interface features. The second video gives additional information of how to set the IQ3 actuator while using the Bluetooth remote. Several additional IQ3 videos are shown further down on this page.

How to Set the IQ3 Actuator

The IQ3 is suitable for indoor and outdoor use at ambient temperatures of -33C (22F) to 70C (140F) and a relative humidity of 100%. The IQ3 o-ring seals offer watertightness to IP66/IP68 7m for 72 hours, NEMA 4, 6 plus protection from dust and moisture when the terminal cover is removed for on-site cabling.

All external fasteners on the IQ3 are of plated stainless steel. The integral motor is of a low enertia high torque design specifically for valve acuators. Available electrical requirements are single phase (all standard voltages from 100v to 240v), three wire three phase (all standard voltages from 200v to 690v), and direct current (24v, 48v, and 110v). Voltage tolerance is +/-10%, with a frequency tolerance of +/-5%, and a maximum starting voltage drop of 15%. Please contact us for additional information of how to choose an actuator for use in environments that may not have standard supply voltages. The IQ3's motor safety switching includes lost phase protection, phase rotation correction, high temperature auto-reset, and stall de-energizing within 8 seconds of a stall.
