I need to go inspect a batch of valves in a few days; I’m not sure what to check Those who know can share, thanks!
Generally, an unpacking inspection involves checking the appearance for any damage or rust, ensuring that all accessories of the valve are present, and verifying that technical parameters such as material, model, specifications, CV value, and flange grade meet the requirements specified in the technical documents. It also checks whether all necessary documentation and certificates are available, as well as whether sufficient spare parts are present; in essence, it is a handover procedure.

First is the visual inspection, to check whether the valve’s model and specifications match your requirements, and whether technical documents such as the factory certificate and test reports are complete. Conduct actual spot checks on the valves if possible.
Generally, the appearance is inspected. Compare the supply list with the contract or agreement.
Please refer to the standards SHT3064-2003 \"Selection, Inspection, and Acceptance of General Steel Valves in the Petrochemical Industry\" and SH3518-2000 \"Procedures for Valve Inspection and Management\"; these two standards can help you solve the problem.
When we open the package for inspection, we only check the appearance and quantity; for certain requirements, a spectrometer is used to examine the material of the valves. Compression test to check the leakage level is conducted on a random basis
