Nuclear grade valve
Nuclear gate valves can be used in the main circuit of 1,000kw pressurized water reactor nuclear power plant and its auxiliary system pipeline to perform system safety functions to prevent and slow the escape of radioactive materials in the containment after water loss accident. The valves are safety grade 2 and grade 3, standard grade 2 and grade 3, and the seismic class is type 1A and type 1I. The prototype of foss nuclear gate valve has passed 2000 tests of thermal life, thermal cycle, fluid blockage, earthquake and end loading test, which can meet various functional requirements under operating conditions.
