Fluid Power Actuators in Project to Provide Energy Independence for Chile

Rotork’s (UK) fluid power valve actuators have been installed throughout a major new LNG (Liquefied Natural Gas) importing and distribution project that is expected to meet 40% of the demand for gas in Chile
and secure energy independence for the country. 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.

Rotork Fluid Systems has received orders for heavy duty, scotch-yoke pneumatic, gas-over-oil and high pressure gas actuators which have been supplied to valvemakers in France, Italy and Spain. The majority of the eighty-seven CP and GP range pneumatic actuators supplied are operating cryogenic service ball and butterfly valves at the Quintero Bay marine terminal and the adjacent storage and regassification plant.

The GO range gas-over-oil and HPG range high pressure gas actuators have been supplied for a new 28 kilometre 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 24inch ball valve at the City Gate in the Quintero LNG terminal, whilst the HPGs are installed on Class 600 8inch and Class 300 12inch 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.

The sales and engineering participation of Rotork’s local representative in Chile, Ineco, S.p.A, has been a key factor in the company’s success with this important project. Rotork’s activity was co-ordinated at Rotork’s USA head office in Rochester and involved.
