Direct-drive and geared handwheels are sized for effective manual operation of the valve. Handwheel drive is independent of the motor drive and is selected with a lockable lever for safe operation even when the motor is running. See Section 9.1. Patented absolute position encoder is provided to enable robust, high accuracy measurement of up to 8,000 actuator output rotations under all conditions, including loss of mains power. See Section 9.7. 2. Environmental sealing IP66/68; 7 m for 72 hours State-of-the-art piezo torque sensor for IQ provides reliable torque measurement over a wide temperature...

Actuator selection for part-turn valve types Actuator selection for part-turn valve types: Butterfly, ball, plug, damper. Torque range - actuator availability Direct Torque Class / starts-hour With IW/MOW gearbox Torque Class / starts-hour Direct - control valve Torque Class / starts-hour IQT Fail-to-position options IQT, IQTM and IQTF actuators are compatible with two fail-to-position solutions. The Shutdown Battery option is suitable for use in hazardous and safe areas. The Battery Backup option is suitable for use in safe areas only. Both fail-to-position solutions will perform a preconfigured...

Design features Simple, secure commissioning and configuration Technological advances Ensuring correct configuration and keeping it secure is the bedrock of reliable operation. All IQ3 Pro actuators can be set up non-intrusively using the Rotork app on a smartphone, Rotork Bluetooth® Setting Tool Pro (BTST) handset or via manual setup using the actuator control knobs. Torque levels, position limits, control and indication functions can all be accessed using any of these setting options. Bluetooth wireless connectivity with a smartphone or BTST allows easy use without direct line-of-sight, however...

Unrivalled industry-leading reliability Asset management Valve operation must be reliable. Rotork IQ3 Pro range actuators are engineered for a lifetime of uninterrupted service in the toughest applications. Built on the Rotork drive train, proven since 1957, IQ3 Pro range actuators retain industry leading reliability: With an advanced display, position, torque, status and configuration data is clear and immediately accessible. In addition, the valve, actuator and process data is available in real-time on screen or in the control room. Valve stroke torque/thrust graphs, duty trend logs, vibration...

Design features Indication power With the absolute encoder, a battery is not required for position sensing and tracking. As all configuration and data logger data is stored in non-volatile EEPROM memory, all settings are safe when no power is available. However, to maintain the display and ensure remote indication is kept updated, allow datalogging and power off commissioning, an indication battery is included as standard. Reduced power consumption means the battery has an exceptionally long life and low-cost replacements are available from suppliers globally. In addition, the auxiliary power...

Remote field operation The Remote Hand Station Pro (RHS Pro) uses the same display and controls interface as the IQ3 Pro actuator, allowing users to remotely operate, interrogate and configure the actuator from up to 100 m distance. Due to the familiar, featurerich interface, set up could not be simpler using the Rotork Bluetooth® Setting Tool Pro supplied with the IQ actuator, Rotork app or manual setup using the local control knobs. In the event of overheating, two thermostats embedded in the motor windings directly sense the temperature and trip the actuator control circuit. Duplicating the...

Design features Vibration measurement Lifetime support Vibration can severely affect the performance and lifetime of plant equipment and its effects are cumulative. Levels of vibration can vary significantly, depending on process conditions such as start up and shutdown, valve cavitation and at different flow rates, making it difficult to capture with mobile measuring devices. With communication featuring Bluetooth wireless technology, the onboard data logger and the new dual-stacked display, the IQ range offers unrivalled support to provide complete product backup with local analysis and configuration....
