Rotork Australia presents a new gas over oil actuator solution, the Rotork GO range of pipeline actuators designed to use pipeline gas as the motive power source.
The gas is delivered to the oil tanks and gets converted into hydraulic pressure. The pressurised hydraulic oil is used to drive Rotork’s industry recognised and proven 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 and are available in fail-safe versions. The standard gas control systems are complemented by 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 600,000Nm quarter-turn or 5,000,000N for a linear application.
