Rotork Actuators

K-TORK Air Fail-Safe actuators incorporate an integral air reservoir to fail valve in desired position upon loss of air pressure, electrical power, or both. Available for general purpose or hazardous area classification installations.

K-TORK offers a de-clutch gearbox manual override that mounts between the actuator and the valve to provide for manual valve operation in the event of air failure or for emergency operation. Under normal automatic operation, the gear is disengaged and the actuator turns freely to operate the valve.

The Ranger CG actuators provide an armoured layer of protection against a wide range of acids, caustics, alkalis, solvents and salt-laden environments. The cast aluminium body and alloy steel vane are treated with a thermosetting tripolymer resin coating system formulated for mechanical components requiring corrosion-resistance and surface lubrication.

The IQ3 features legendary innovations including Rotork's unique double-sealed enclosure, ‘non-intrusive' infrared commissioning, datalogging and predictive maintenance capabilities. More recent innovations include the advanced display, Bluetooth® communications interface and absolute encode

Backwards compatibility for SyncroSET actuators is part of Rotork’s commitment to working with our customers to understand the full life cycle of their assets. The IQ3 SET feature facilitates obsolescence management and future-proofs plants without affecting the plant infrastructure.

IQ3D actuators are direct current powered versions of IQ actuators. Direct torque range 11 Nm to 305 Nm (8 lbf.ft to 225 lbf.ft). Voltage ranges available are 24, 48 and 110 VDC.

Based on the multi-turn IQ actuator, IQH provides a range of high output speed actuators with integral epicyclic gearing. Gearing is optimised to be irreversible and provide a self-locking function for the valve.

The modulating version of the IQ 3-phase electric actuator has a solid state reversing starter in place of the electro mechanical contactors. It features fast-response remote control circuits for rapid control. To optimise positional control, the solid state starter also adds an electronic motor ‘brake' feature.

Benefiting from all the features of the IQM 3-phase electric actuator, the IQML has a linear output drive providing seating thrust output of up to 43 kN (9,667 lbf).

IQ3S is the 1-phase version of the IQ3 actuator. Direct torque range from 10 Nm to 450 Nm (7 lbf.ft to 332 lbf.ft).

IQT part-turn 3-phase, 1-phase and DC electric actuators are designed for isolation or regulation duties (S2 & S3/Class A & B) of up to 1,200 starts per hour.

The IQT Battery Backup actuator provides valve fail-safe 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 24 VDC supply allowing control of the valve to the pre-configured position.

The IQT shutdown battery option provides fail-to-position functionality for IQT actuators in the event of a mains power loss in hazardous and non-hazardous environments. The IQT shutdown battery option is part of the IQT range of actuators (the part turn option of our flagship range of intelligent electric actuators). The integral battery pack provides a compact, explosionproof shutdown solution.

IQTF electric modulating actuators are capable of multi-turn, rising output, linear output and direct rotary output. Includes special fast switching control inputs for hardwired control.

The modulating version of the IQT electric actuator is designed for modulating duty up to (S4/Class C). It features fast-response remote control circuits for rapid control.

Specifically designed to meet the needs of modern warship design, IQTN range actuator have been independently tested for shock tolerance and meet the requirements of most worldwide surface ship applications.

The RC200 is an extremely compact pneumatic actuator. Its scotch yoke design is particularly suited for valves with high start or end torque requirements. It is available in double-acting and spring-return configurations with torque output up to 4,400 Nm (38,000 lbf.in).

Designed for 3-position control of dosing valves or emergency shut-down (EDS) valves where a partial stroke test (PST) is demanded, the RC-DOS actuator is built on the well-known and highly reliable scotch-yoke principle. For 90° valves up to 660 Nm (5,841 lbf.in) closing torque at 6 bar.

The RC88 is an extremely high torque, compact, pneumatic quarter-turn actuator. Its scotch yoke design is particularly suited for valves with high start or end torque requirements. It is available in double-acting and spring-return configurations with torque output up to 7,600 Nm (67,000 lbf.in).

Remote Control RCC200 pneumatic steel epoxy coated actuator for offshore, petrochemical and other industrial hard conditions. Available as single or double acting and up to 900 Nm (7,965 lbf.in).

Designed for demanding applications the RC200 fire safe actuator range is ideal for applications, where an extreme heat resistant actuator is required. The RCC200 is suitable for temperature range up to 1000c for up to 1 hour or continuous duty at up to 150 °C ambient temperatures. With a high temperature rating of up to 1000c it provides shortly protecting in the event of a fire and is ideal for safety critical systems.

RCE-SR electro-hydraulic actuators is a range of rigid actuators for on/off and positioning with high torques in relation to size. Torques ranging from 50-5,000 Nm (44,248 lbf.in) The function is a cost effective alternative to a spring return electric actuator.

The RHS enables safe and secure local monitoring and control of Rotork IQ3 Range actuators installed in inaccessible locations. Using the same display and controls interface from the IQ3, users can remotely operate, interrogate and configure the IQ actuator from up to 100 m distance.
