Rotork IQTF Full-Turn Actuator

The Rotork IQTF Full-Turn Actuator range are electric modulating actuators capable of multi-turn, rising output, linear output and direct rotary output. Includes special fast switching control inputs for hardwired control. Other Rotork IQT Actuators are available in our full range.

Engineered for choke and control valve applications, Rotork’s IQTF actuators provide reliable flow control for oil and gas or process operations, capable of achieving accuracy to 0.3% and resolution to 0.1%. A highly accurate absolute position sensor can measure up to 22 output turns independent of electrical power.

The series of actuator is installed on the wellhead choke valve. The remote location of the wells means a DC power supply using a solar system and battery pack is being used to power the IQTF actuators. This solution was specified as a more reliable option than hydraulic or pneumatic actuation as it avoids potential leakage common in hydraulic actuators and also power supply not available. This option is greet where plenty of sun to use as a source.

Rotork’s lightweight, compact IQTF actuator provides fast and accurate valve control and can perform up to 1,800 starts per hour, an important factor given the need for a tight well flow threshold to avoid over pressure in the main trunkline.
