Rotork IQT intelligent part-turn valve actuator

Rotork’s IQT intelligent part-turn valve actuator has been upgraded with a range of data logging and communication capabilities.

Diagnostic graphics present the valve torque, usage profiles and service logs. Local position indication, valve and actuator status, asset management and diagnostic operating information is available to download and can be viewed directly on the actuator’s LCD display.

The software can save predefined sets of instructions and settings to apply to multiple actuators requiring the same configuration.

Valve maintenance requirements can be identified and anticipated, eliminating unplanned interruptions to the process. Data includes valve torque profiles, operational start profiles, vibration and temperature trend logs and an event log. Specific asset management information includes running time, average torque and number of starts. Service or maintenance alarms are selectable from configurable menus including open and close torque levels, total starts and vibration levels.

The actuators are suitable for three-phase, single-phase or DC power supplies, with a torque output range of 50 to 2000 Nm available for isolating, regulating and modulating duties. The output speed can be non-intrusively adjusted over a 4:1 range without affecting the output torque. All valve interface bases conform to ISO5211 and are fitted with removable couplings.

Hazardous area actuators are approved to the latest IEC Ex standards. Network connectivity options include Foundation Fieldbus, Profibus, HART and DeviceNet open systems, as well as Rotork’s Pakscan wired or wireless systems.
