Rotork Electric Actuators

Rotork Electric Actuators

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.

Rotork Electric Actuators Fire Protection
Rotork has the experience, know-how and product range to deliver virtually any actuation solution. Rotork products have long been chosen for their reliability and performance. Whilst these proven characteristics are certain under normal operating conditions, there are conditions that not even a standard Rotork actuator can operate in — fire. Fire and explosion is a major cause of concern to refinery, gas processing, petro-chemical and offshore installations. Danger and damage from fire can be minimised by the efficient and effective protection of the systems, which control the plant. For this reason Rotork can recommend a range of fire proofing options for it’s actuators, ranging from fixed passive protection through to full fire retardant enclosures.

Rotork Electric Actuators IQH High Speed
Based on the multi-turn IQ actuator the IQH provides a range of high output speeds while being generally irreversible and therefore provides a self-locking* ability by the actuator for the valve. Developed for diverter valves in meter prover applications, IQH provides fast operation with positive seating without backdriving. IQH Pro actuators offer the following powerful features: Multi-turn and quarter-turn High speed - self locking capability Non-intrusive set-up Clear user friendly controls and indication Simplified torque and position control for increased reliability Flexible and comprehensive control and indication On-board datalogger IrDA compatible for local and remote actuator analysis via PC IQ insight & IQ Pocket Insight software tools for set-up, analysis, asset management and diagnostics *Note:It should be noted that a self-locking ability cannot be guaranteed for worm and wheel drives under all conditions including high loads and vibration, either under static and dynamic conditions. When handwheel operation is selected the gear train is disconnected and therefore any locking ability will be lost.

Rotork Electric Actuators IQM Modulating
Benefiting from all the features of the IQ, the IQM modulating version has a solid state reversing starter in place of the electromechanical contactors. “Hammerblow” lost motion drive is removed and fast response remote control circuits for rapid control are included. The IQM is suitable for up to 1,200 starts per hour. The solid state starter also adds an electronic motor ‘brake’ feature, improving positional control.     IQ10, 12, 18 (Size 1)     IQ20, 25 (Size 2)     IQ35 (Size 3)     IQ40 (Size 4)     IQ70     IQ90     IQ91     IQ95

Includes special fast switching control inputs for hardwired control. IQTFM Pro actuators offer the following powerful features: Multi-turn and part-turn Slow speed operation for increased accuracy Non-intrusive set-up Clear user friendly controls and indication Simplified torque and position control for increased reliability

Rotork Electric Actuators IQTFS Fail Safe
The IQT Failsafe actuator provides valve failsafe operation by utilising power from a battery source during AC supply mains failure. Under normal supply conditions the actuator operates from the site AC electrical supply. On loss of this supply the actuator automatically switches over to receive power from a 24V DC supply allowing control of the valve to the mains failsafe position. IQT Failsafe Pro Type 1 - External Failsafe Suitable for use in hazardous and nonhazardous locations, Type 1 includes connection for a customer supplied 24V DC supply in addition to the normal AC supply. IQT Failsafe Pro Type 2 - Battery Failsafe Suitable for use in non-hazardous locations only, Type 2 includes a battery located in the actuator terminal cover, charged from an integral charging system when AC power is applied to the actuator. IQT Failsafe Pro offers the following powerful features:   Same performance as Standard IQT Three Phase, Single Phase and DC power supplies (type 1 only) Modulating Duty Option Full-turn and multiport option
