Recently, the first PRVR ( pressure relief valve ) undertaken by Hefei Keju Cryogenic Technology Co., Ltd. has been successfully produced and tested.

PRVR is an important component of ITER FEEDER, connected to CTB (coil terminal box), responsible for the pressure relief of the entire system, and is an important safety component. The types of valves in PRVR are the most diverse among FEEDER components, with complex functions and high technical specifications and testing requirements.

Since undertaking the project, the company has completed the complete process from design to production to testing. In design, the selection and design changes of all valve components have been completed, and all drawings and production documents have been prepared; In production, a large number of production difficulties have been solved and production has been successfully completed; In testing, the engineering designers designed a complete testing plan and completed the acceptance testing of PRVR.

PRVR production is another important FEEDER procurement package task undertaken by the company. The successful completion of the first PRVR has opened a good start for the production of over 20 PRVR units in the future.
