Emerson Process Management has been serving the nuclear industry for more than 40 years. The company's Fisher nuclear control valve series is used in 90% of the world's nuclear power plants with excellent reliability. Today, with the size of the enterprise and the expansion of the specialized network of many nuclear applications around the world, Emerson has become the brand name for many next-generation nuclear power plant projects.
The Emerson Innovation Center in Marshallton, Iowa, United States, has a flow testing lab. The test equipment in the lab can use its piping configuration and flow capacity to simulate a large nuclear reactor design piping system, and measure the performance of Fisher's next-generation nuclear power control valves under customer-defined conditions in the test piping system. We can guarantee this extensive rigorous testing and the opportunity to witness the reliability of control valves.
Characteristics of reliability.
Utilize existing/tried-tested valve actuation methods and selection principles.
The newly designed control valve has a low center of gravity and better seismic performance, which can meet the seismic requirements of the three-axis 6G seismic acceleration of the third-generation nuclear power plant
The ultra-high purity graphite filling system maintains the integrity of the stem seal with the option of dynamically loaded spring sealing
Bellows sealing can be selected for specific situations/media
The valve body/stem is welded to each other.
Security you can trust.
At present, the market has put forward strict requirements for the safety and reliability of nuclear power control valves and instruments. Fisher's new generation of nuclear power control valves and accessories are designed in accordance with international mainstream nuclear power regulations and standards and new nuclear power technical requirements, through conservative calculation analysis and rigorous design qualification tests, can meet the strict requirements of the new generation of nuclear power control valves.
The safety of the special
Spring-return pneumatic actuators enable important safety-related functions.
The professional installation position design makes it easy to inspect parts and other parts, simplifies maintenance, and avoids inspectors staying in the safety box for long periods of time.
Choose metal seals and seats that can be closed for a long time even in the event of an accident.
Effectively improve the economy.
Choosing Fisher's new generation of nuclear electrical control valves and instrumentation can dramatically increase uptime. Emerson's Fisher next-generation nuclear valve kits and retention solutions ensure long-term quality and durability while meeting the short- and long-term needs of our customers' nuclear businesses. Combined with the industry's FIELDVUE digital valve controller and TopWorx' G0Switch proximity limit switches.
Cost-effective features.
The rotary valve is designed to be end-inlet mounted, simplifying maintenance by eliminating the need to remove the actuator from the pipe when replacing the internal parts of the valve. The actuator can be easily removed without special tools, and the valve internals can be quickly replaced, which can significantly reduce stopping times.
