Pipelines present a number of operational requirements demanding specialised actuation solutions. These include actuation of valves in remote areas, where mains power sources are not available, and actuators to provide vital failsafe and safety shutdown duties, which are often in remote locations.

For 60 years Rotork has manufactured electric and fluid power actuators for pipeline flow control in areas with and without mains power availability. Rotork has also developed innovative and reliable actuator designs to meet specific pipeline safety and shutdown duties in the most demanding environments. This article will focus on these actuators.
