Product Introduction

Overview of Rotork IQT

The Rotork IQT actuator is a high-performance part-turn actuator designed for quarter-turn valves such as ball, butterfly, and plug valves. Combining rugged mechanical design with advanced intelligent controls, the IQT ensures fast, precise, and safe valve operation in critical industrial environments. Its flameproof construction and robust housing make it suitable for demanding conditions, including offshore, chemical, and power generation applications.

Technical Specifications and Mechanical Features

Feature	Specification
Torque Range	50 Nm – 1,500 Nm
Max Starts per Hour	1,200 c/h
Swing Angle	75° – 105°
Operating Time (90°)	5 – 50 seconds
Duty Type	On/Off and positioning duty
Power Supply	3-phase AC
Sensors	Absolute position sensor; torque sensor for accurate feedback
Manual Override	Integrated handwheel for emergency operation
Enclosure	Flameproof, corrosion-resistant, suitable for hazardous areas

The IQT actuator's absolute position sensor provides precise valve angle measurement, while the torque sensor monitors operating torque in real time. These sensors allow intelligent control modules to regulate speed, detect obstructions, and provide predictive diagnostics.

Operational Advantages and Comparison

Compared to traditional part-turn actuators, the IQT delivers:
Faster response times with smooth valve movement
Enhanced safety, preventing over-torque and mechanical stress
Reduced maintenance due to simplified internal wiring and robust components
Data-driven insights via integrated diagnostics and real-time monitoring
The IQT outperforms standard quarter-turn actuators by combining intelligent control, precise torque management, and high-frequency start capability, making it ideal for mission-critical systems requiring reliable on/off or positioning control.

Applications

The IQT actuator is widely used in:
Oil & gas pipelines (ball & butterfly valves)
Petrochemical and refining plants
Water treatment and distribution networks
Offshore and power generation facilities
Industrial automation requiring rapid, precise valve control
With its robust construction, intelligent sensors, and operational transparency, the Rotork IQT actuator ensures safe, efficient, and reliable valve operation under challenging industrial conditions.
