New features added to intelligent actuators

08 March 2024

Rotork has added new features to its IQ3 Pro range of intelligent actuators. These include increased speeds for the IQT3F Pro electric modulating actuators, independent open/close speeds for part-turn actuators and closed-loop control for the multi-turn and part-turn actuators.

The optional increased speed for the IQT3F Pro electric modulating actuators is available for sizes 50, 100 and 125. Adjustable speed, including a slow mode for accurate positioning and a high-speed option where faster speeds are required, making them suitable for choke valve applications.

With the independent open/close speeds, it is possible to configure IQ3 Pro part-turn actuators' speed settings for clockwise and anti-clockwise rotation.

Another feature added is closed-loop control. Closed-loop control takes the on-off/bang-bang control or PID control methodologies typically used in a PLC or discrete PID controller and incorporates them into the range. Multi-turn non-modulating IQ3 Pro actuators use a setpoint positioning method known as ‘bang-bang’, while part-turn IQT3 Pro and IQ3M Pro actuators use the PID closed-loop control method.
