Rotork Controls is the home of the flagship IQ intelligent electric actuator range. The IQ range features legendary innovations including Rotork's unique double-sealed enclosure, ‘non-intrusive' infra-red commissioning, data-logging and predictive maintenance capabilities. More recent innovations include the advanced display, Bluetooth® communications interface and absolute encoder.
The IQ functionality and reliability is available for valves of virtually every size and description, including multi-turn (rotary), quarter-turn, isolating and modulating, with watertight and hazardous area approvals to all internationally recognised standards.
Electric actuator ranges also include the AWT for simplified control duties, ROM, ROMpak and Q direct drive actuators for small quarter-turn valves and IEEE qualified NA actuators for the nuclear power industry.
Rotork actuators are compatible with a wide range of communication and process control systems. Rotork's own Pakscan system offers advanced actuator network control similar to network control from Profibus, Foundation Fieldbus, Modbus, DeviceNet and Hart.
Specifically designed to meet the needs of modern warship design, the IQTN has been independently tested for shock tolerance and meets the requirements of most worldwide surface ship applications.
The Rotork IQTN actuator offers a low cost, reliable, virtually maintenance free, light weight 'fit and forget' solution which offers a myriad of control options fitting with the management of shipboard critical systems.
The IQTN actuator offers the following powerful features:
Three phase and Single phase power supplies
Modulating duty option
Full-turn and multiport option
Shock tolerant
Compact design
Environmental protection to IP68 (7 mtr for 72 hours)
Various optional upgrades are available including:
Fire Protection exceeding ANSI/API607 and UL1709 (1093 degC / 2000 degF for 30 minutes). Please consult Rotork for various options such as semi-rigid enclosures (blankets). Intumescent coating is not available for this product.
Rotork NA range actuators have been qualified for safety related duty in nuclear reactor installations. The qualification is in accordance with US standard IEEE 382, 1980.
Rotork type NA actuators have been manufactured in strict accordance with the latest quality procedures for use in nuclear environments.

Rugged compact, double-sealed
Positive travel limitation through externally adjustable mechanical stops
Marine option
Simple remote control for basic applications
ROM actuators provide quiet and reliable operation for all kinds of small ball valves and butterfly valves, as well as dampers and ventilation louvres. They provide self-locking as standard, local visual indicators and manual override options together with a wide range of voltages.
Torque range 35 to 650 Nm (25 to 480 lbf-ft).
Efficient yet simple gearing
Wide range of supply voltages available
Single-phase, three-phase and DC options
Watertight IP68 rating
Building on the simple specification of the ROM / RBM range, Rotork now offer a more complete control solution with the introduction of the new ROMpak.
ROMpak introduces: Local controls for ease of operation; Dual local indicators – mechanical and LED; Phase rotation correction for ease of installation; Options including: bus communication and Folomatic/CPT.
Torque range 35 to 650 Nm (25 to 480 lbf-ft).
Efficient yet simple gearing
Wide range of supply voltages available
Single-phase, three-phase and DC options
Watertight IP68 rating
