The valve is made under pressure test at home with the unpainted condition to detect leaks caused by non-tightness between details, especially underground cracks (microcrack) inside that the naked eye or NDE methods are not detectable.
Pressure test valves according to API 598, API 527, API 6D, ANSI/FCI 70-2, ASME B16.34, ASME B31.3… and VILAS certification.
