Rotork K-Tork Range - Pneumatic Valve Actuator

Brand: Rotork PLC

K-TORK Actuators and Controls represents the future of valve automation.

The vane actuator is a ‘True Rotary’ actuator that does not require the conversion of a linear motion to a rotary motion.

The result is a simple, highly accurate and reliable quarter-turn pneumatic actuator that is specified for the most demanding process flow control applications.
