DN100 Wafer Butterfly Valve D71X-16Q | Seal Test & Protective Jacket Fit

A factory QC overview of a DN100 D71X-16Q wafer-type butterfly valve, including actual sealing-test footage, protective-jacket fitting and product views. The order inspection sheet identifies the valve as D71X-16Q, DN100, and records a protective jacket supplied for this valve. The sealing-test source video is labeled 1.78 MPa; this source filename should not be treated as a verified rated working pressure or independent acceptance certificate. The source order review also records confirmation of the heat number, pressure and appearance. Detailed selection should still be based on the approved drawing and order-specific inspection record.
