Verification is required, and it must also be carried out periodically at qualified departments
New ones also need to be taken to a calibration facility for verification before they can be used, and regular calibration is required

It is necessary to have it checked by a testing facility; in accordance with the system requirements, the relevant parameters must be provided to this facility so that the safety valve can be calibrated and sealed with a lead seal. Installation can only proceed after a calibration report is issued.
The newly purchased ones come with lead seals; do they also need to be calibrated before installation?
It needs to be verified, and it is also necessary to take it to a qualified department for verification on a regular basis.
