Flowserve Corporation says it received three orders totalling more than $10 million from China Nuclear Power Engineering Company Ltd. (CNPEC) for nuclear main steam isolation valves (MSIVs) in the second quarter of 2010.

The valves are intended for use at three CPR-1000 plants: Yangjiang units 3 &4, Fangchenggang units 1&2, and Ningde units 3&4.

“China remains an important aspect of our global growth strategy and these orders demonstrate our continued leadership position in this market,” said Tom Pajonas, president, Flowserve Flow Control Division.

Flowserve MSIVs are specially designed, large gate valves with fast-acting, stored energy actuators. They are designed for installation in a plant’s nuclear steam supply system where their primary function is to close within 3 to 5 seconds in the unlikely event of a rupture in the steam piping. The valves will be manufactured at the Flowserve facility in Raleigh, North Carolina, and are scheduled for delivery to China in 2011 and 2012.

In April, Flowserve announced a separate multimillion-dollar order from CNPEC for main steam isolation valves, main feedwater isolation valves and feedwater motor-operated valves to be used at Taishan units 1&2.
