Fisher valves used in this critical system will help maintain reactor feedwater flow
MARSHALLTOWN, IOWA (February 24, 2010) – Emerson Process Management has been awarded a multi-million dollar purchase order from State Nuclear Power Engineering Corporation (SNPEC) for critical Fisher® control valves to be used in Westinghouse AP1000™ pressurized water reactors at both the Sanmen 2 and Haiyang 2 nuclear power plants in China.
The order includes valves for two applications at each plant: a start-up or bypass valve and the main feedwater valve. The bypass valve is a specially-designed six-inch valve with a seismically qualified actuator and special trim to ensure a smooth transition with the main regulation valve. The main feedwater valve is a 20- by 16-inch valve with specially characterized trim and actuation to ensure rapid but stable response. The actuators for both valves have been sized using EPRI guidelines to meet industry standards.
For over 35 years, Emerson has supported nuclear facilities worldwide with Fisher nuclear valves and associated services. In fact, Fisher valves are installed in over 90% of the world’s nuclear facilities. To date, thousands of Fisher ASME Section III N-Stamped and RCCM process control valves have been installed around the globe.
