Rotork expands its IQ range of electric actuators

Rotork has introduced a new model in its IQ range of non-intrusive intelligent electric actuators with an optimised combination of valve stem diameter acceptance and torque output.

The new IQ19 actuator facilitates economical automation of valves and penstocks typically found in the water and effluent treatment industries.

The actuator combines a stem acceptance of up to 51mm diameter with torque output up to 135Nm and output speeds up to 72 rpm @ 50Hz (86 rpm @ 60Hz).

The combination meets the operating requirements of large numbers of penstocks, sluice gates, and gate valves.

The actuator incorporates the full range of advanced reliability, functionality, and asset management features, including an unrivalled range of data logging capabilities.

A backlit display is the focus of attention for non-intrusive wireless commissioning, communication, and multi-functional indication, including multi-lingual menus for setting-up and configuration.

Local position indication, valve and actuator status, asset management, and diagnostic operating information is available to download or to be viewed directly at the actuator.

Diagnostic graphics present a window into the plant, showing the valve torque, usage profiles, and service logs, facilitating real-time analysis directly at the actuator and in the control room.

Preventative valve maintenance requirements can be identified, eliminating unplanned interruptions to the plant or over-cautious planned maintenance outages.

Reliability is optimised by the IQ double-sealed IP66/IP68 watertight and temporarily submersible enclosure, which permanently protects internal electrics from the ambient environment, even during site wiring with the terminal housing cover removed.
