A Rotork electro-hydraulic actuator has been installed at an energy generation company’s hydro-electric plant in the heart of a Spanish mountain range.

A Rotork Skilmatic actuator is being used to operate a critical butterfly valve installed on a pipeline feeding the power plant’s turbine at the Repsol site, which is located high up in the Picos de Europa mountains.

The actuator has been installed on the Naranjo de Bulnes peak, which reaches a summit of 2,518 metres above sea level, in Camarmena, an area in the northern Spanish principality of Asturias. 

The site’s height and access difficulties made the installation tough but the hard work of Rotork’s service engineers from the Spanish office ensured that the installation was successful, demonstrating Rotork’s versatility and ability to overcome challenges.

Rotork’s SI actuators offer a reliable way to carry out analogue control for both quarter-turn and linear valves and dampers. The actuators combine the simplicity of electrical operation with hydraulic precision and the reliability of spring-return or accumulator fail-safe action.
