RWE npower has awarded a framework agreement to Rotork Site Services for the supply of Rotork valve actuators and actuation maintenance services throughout all of its UK fossil-fuelled and cogen power stations. The contract has been awarded to Exeeco Ltd, a Rotork group company with over thirty years of specialist experience of valve actuation services in the power generation industry. Exeeco has been installing Rotork Skilmatic SI electro-hydraulic failsafe actuators to improve valve performance in critical areas such as the mill isolation dampers. Elsewhere at Aberthaw, feed water regulation valves with pneumatic actuators, which were causing operational problems and proving uneconomical to maintain, have been replaced. The new valves are fitted with Skilmatic SI electric-hydraulic modulating linear actuators that match the technical requirements for high thrust, fast acting and accurate valve positioning. Rotork IQ and IQT actuators have also been recently installed on applications including feed system valves, boiler valves and quarter-turn dampers.
