Purge Valve for Great Wall Poer: Carbon Steel
This purge valve for the Great Wall Poer is specified around carbon steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is a specification nobody had written down, or a fitment that looked right on paper and failed on the bench. Both are specification problems, and both are preventable.
