Supplier responsibilities: Equipment scope
The named manufacturer confirms body, trim, elastomers, connection, inlet and reduced-pressure ranges, and which strainers, sensing lines and downstream protection are included. Working pressure and flow rate must be restated against the buyer’s inlet variation and turndown, not copied from a generic family table. If the duty is hydraulic oil, the manufacturer must cite seal and trim evidence for that oil and temperature; a Watts water-valve page is not that evidence. Feedstock here is the process fluid entering the valve, including water quality or steam condition.
