IQT quarter-turn actuators

IQT

IQT actuators are direct drive quarter-turn electric actuators which can be used for isolation or regulating duties of up to 60 starts per hour. IQT’s are watertight or watertight and explosionproof depending upon specification. Torque output from 50 Nm (37 lbf ft) to 2,000 Nm (1,476 lbf ft).

IQT Fail Safe

The IQT Failsafe actuator provides valve failsafe operation by utilising power from an internal battery 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 V DC supply allowing control of the valve to the failsafe position. For detailed information see publication E116E

The IQT range

The IQT (IQ quarter-turn) is the result of ongoing commitment to product development at the cutting edge of new technology.Maintaining the simple commissioning and troubleshooting design of the Rotork IQ (see left), the new IQT introduces a direct drive, quarter turn actuator—offering the highest standards in comprehensive control, access to real time diagnostics and comprehensive bus compatibility.

IQTM

The modulating version of the IQT has solid state motor switching and includes fast response remote control circuits for rapid response to control signals. The IQTM is suitable for up to 1,200 starts per hour.

IQT features: IQTF

t Direct drive quarter-turn The IQTF provides extended output rotation for part turn valve types requiring more than 90° for operation. Typical valves include 180° and 270° diverter valves and multiport manifolds requiring bi-directional 360° operation. The IQTF actuator has a low output speed for increased positional accuracy.The IQTF may also be utilised for low turn, multiturn applications where slow operation is required. t Three phase, direct current and single phase actuators t Multilingual text display for status and setup t On-board data logger included as standard For detailed information see publication E119E t IrDA
™ compatible for local and remote actuator analysis via InSight PC software t Clear, user friendly controls and indication t Simplified torque and position control for increased reliability

IQTN

t Comprehensive control and flexibility The IQTN has been developed to meet the specialist demands of nautical & military applications within a standard package. Retaining all the features of the IQT the IQTN has a shorter electronics cover for confined on-board spaces and an anti- shock base. t Approved for use in SIL applications
