Export valve quality is created across the production process, not only at final inspection. Material identification, machining tolerances, sealing surfaces, assembly cleanliness and controlled tightening all affect service performance.
Inspection stages
A structured plan normally covers incoming components, machining dimensions, assembly, shell and seat pressure tests, operation checks, coating inspection, nameplates and packing. Requirements should be agreed before production so that hold points and witness inspections can be scheduled without delaying shipment.
Records for professional buyers
Depending on the project, the document package can include drawings, material records, pressure-test reports, coating data, inspection photographs, packing lists and certificates of conformity. GREYSEN coordinates these items for distributors, contractors and OEM customers.
