Intelligent part-turn valve actuator

Written by: Tom Austin-Morgan | Published:

Rotork has introduced the IQT electric valve actuator bringing the functionality and asset management capabilities of Rotork's 3rd generation intelligent technology to the direct-drive operation of part-turn valves.

Its absolute encoder tracks valve position without the requirement for a battery even when there is loss of power. If an actuator is manually operated during a power outage, the local display and remote indication is kept updated by the use of a battery which also facilitates data logging and power-off commissioning.

The IQT's double-sealed IP68 watertight and temporarily submersible enclosure is universal to all Rotork actuators, including those with explosion proof certification.

IQT actuators are suitable for three phase, single phase or DC power supplies, with a torque output range of 50 to 2000Nm available for isolating, regulating and modulating duties. In addition, the output speed can be adjusted over a 4:1 range without affecting the output torque. All valve interface bases conform to ISO5211 or MSS SP 101 and are fitted with removable couplings. Hazardous area actuators are fully approved to the latest ATEX standards.

Network connectivity options include Foundation Fieldbus, Profibus, HART and DeviceNet open systems, as well as Rotork's Pakscan wired or wireless systems.
