Rotork K-Tork Range - Pneumatic Valve Actuator
Brand: Rotork PLCK-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.
