Flow control company Rotork has supplied over one hundred IQ intelligent electric valve actuators for the conventional island of the Taishan EPR nuclear power station, under construction in China’s Guangdong Province.

Actuators were supplied for both Velan wedge gate and parallel slide valves, which will perform feed water and steam isolation duties.

The contract included sixteen high speed IQ91 actuators with secondary IS gearboxes fitted to 36 inch Class 900 parallel slide valves for feed water isolation. Weighing in at over 14 tons each, these are the largest pressure seal valves that Velan has ever manufactured.
