Can the new pressure cooker which has been stored for 1 1 year still be used?

As long as the pressure cooker is new and unused, there will definitely be no problem with the metal pot body and lid. However, before use, check whether the pressure reducing valve and sealing ring are naturally aged and fail to play an insurance role. If the sealing ring is aging (mostly made of heat-resistant rubber or polyurethane, it will age itself for too long), a new sealing ring will completely become a new pot.
