3700 Maxiflow Main Steam Safety Valves Feature Optimal Design and Meet the Stringent
Requirements in the Nuclear Power Industry
HOUSTON (November 22, 2010) - Dresser Consolidated® today announced it has been chosen by
Westinghouse Electric Company LLC as the main steam safety valve supplier for four of the company's
AP1000(TM) pressurized water reactors (PWR) in the United States.
The Dresser Consolidated 3700 Maxiflow main steam safety valves will be delivered to AP1000 nuclear
power plant sites in Georgia and South Carolina between 2012 and 2014. The AP1000 reactor is the only
Generation III+ reactor to receive Design Certification from the U.S. Nuclear Regulatory Commission.
The reactors are expected to come online starting in 2016. By discharging steam to atmosphere, the 3700
main steam safety valves will ensure residual heat removal from reactor coolant system via the steam
generator, and secondary side over pressure protection during design basis accidents and transients.

Westinghouse to introduce the next generation of nuclear power solutions back into the United States,
said Nathan Brunell, Vice President of Marketing, Flow Technologies, Dresser Inc. Dresser
