Nuclear check valve
Nuclear check valves can be used in the main circuit of MMW pressurized water reactor nuclear power plant and in the pipeline of its auxiliary system to perform system safety functions to ensure the normal operation of the pipeline system and mitigate the accident consequences. 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. Foss nuclear check valve has the function of actuating dynamic valve, and the prototype has passed 2000 tests of thermal life, thermal cycle, reverse return flow and end loading test comprehensively, which can meet various functional requirements under operating conditions.
