Rotork GO range of gas-over-oil pipeline actuators

The Rotork GO range of pipeline actuators are designed to use the pipeline gas as the motive power source. The gas is delivered to the oil tanks that convert the gas into hydraulic pressure. This pressurised hydraulic oil is used to drive Rotork’s scotch yoke quarter-turn or linear actuators. Using pressurised oil as the driving fluid provides powerful and smooth actuator control and isolates the cylinder from pipeline gas. This prevents contaminants from entering the hydraulic cylinder, eliminating corrosion and seal deterioration, and extending actuator life.

The compact, modular gas control manifolds employ poppet-style control valves - a reliable design trusted throughout the industry - and are available in failsafe versions. The standard gas control systems are complemented with a variety of Rotork Fluid Systems-designed optional equipment and functions including line break, low-pressure close and high differential inhibit. Operation is simple and intuitive.

The GO range is available for up to 600,000 Nm quarter-turn or 5,000,000 Nm for a linear application. This ensures that there will be a size and specification of unit for all applications.
