Rotork’s fluid power valve actuators have been installed throughout a LNG importing and distribution project that is expected to meet 40% of the demand for gas in Chile. The LNG complex at Quintero Bay encompasses the installation of a sea terminal to receive LNG from tankers and a plant for regassifying and distribution by pipelines into central Chile. The GO range gas-over-oil and HPG range high pressure gas actuators have been supplied for a new 28km pipeline which links the Quintero LNG complex to the Electrogas terminal at Quillota for integration with the existing gas network and fuelling combined-cycle power plants operated by Endesa Chile. The GO unit is installed on a Class 600 24in ball valve at the City Gate in the Quintero LNG terminal, whilst the HPGs are installed on Class 600 8in and Class 300 12in ball valves at the Electrogas Plant Gate in Quillota. Designed for safety and shutdown duties, GO and HPG actuators use the pipeline gas as the motive power source. Valve operating speed is adjustable in both directions and manual hydraulic override is provided as standard. All the Rotork actuators supplied are certified to ATEX 94/9/EC and IP66M/67M in accordance with PED 93/27/EC.
