IQ multi-turn actuators

IQ

IQ actuators are multi-turn electric actuators which can be used for isolation or regulating duties of up to 60 starts per hour. IQ’s are watertight or watertight and explosionproof depending upon specification. Direct torque output range from 34 Nm (25 lbf ft ) to 3,000 Nm (2,200 lbf ft).

IQM

The modulating version of the IQ 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.

The IQ range

The Rotork IQ delivers a complete range of actuators suitable for all multi-turn valve applications requiring control and indication flexibility. It offers end users ever higher standards of performance, build quality and overall value.

IQML

Benefiting from all the features of the IQ and IQM actuators, the IQML has a linear output drive providing modulating thrust output of up to 150 kN.

Simple Commissioning

The Rotork IQ provides simple, safe and rapid non-intrusive commissioning with infra-red control. Actuator settings such as torque levels, position limits, control and indication functions can be accessed and adjusted using the “point and shoot” IQ Setting Tool Pro . This supplied, intrinsically safe (IS) tool is unique to Rotork and allows for non-intrusive actuator set-up whatever the environment, power on or off.

IQS

IQS actuators are single phase versions of IQ actuators.Torque range from 65 Nm (48 lbf ft) to 450 Nm (332 lbf ft).

IQD Simple Troubleshooting

The large digital position display clearly indicates real time valve position from a distance. In addition, active valve, control, actuator status and alarm text messages are displayed on the easy to read back-lit display. Using the IQ Setting Tool Pro real-time torque against position profiles and actuator configuration can be accessed during commissioning, adjustment or local valve performance monitoring. The onboard data logger records operational, alarm and valve torque profile data providing valuable information on valve and plant operating performance and conditions. IQD actuators are direct current (DC) versions of IQ actuators.Torque range from 34 Nm (25 lbf ft) to 305 Nm (225 lbf ft).

IQH

The IQH provides a range of high output speeds while being generally irreversible and therefore providing 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.

IQ offers a range of powerful features:
