Abstract: Nuclear class 2 electric three-w ay globe valve is a class 2 nuclear safety-related valve,w hich is used in Safety Injection System( RIS),Reactor and Spent Fuel Pool Cooling and Treatment System( PTR),Chemical and Volume Control System( RCV),Coolant storage and treatment system( TEP),and is one of the key equipment of the third generation PWR units. In this paper,the technical requirements of the nuclear class 2 electric three-w ay globe valve are described,combined w ith the functional requirements of the valve,the research and development process is emphatically described,the key points and difficulties in the design are analyzed,and finally the development of the prototype and performance test verification are completed. The product has been successfully used in the site of nuclear pow er plant. Through the summary of this w ork,this paper provides ideas for the independent design and technical research and development of this kind of electric three-w ay globe valve.
