Product FAQ
Engineering answers
What size and pressure range is the 3/4inch Forged Stainless Steel F304 Socket Welded Swing Check Valve supplied in?
The catalogue series is DN8-DN50 (1/4"-2"), Class 800-2500 / PN133-PN420. A single NPS/class line in the notes is a typical working-size snapshot for drawing discussion, not the series limit. Confirm NPS, class, bore and trim against the approved data sheet.
Which documentation is included in a standard EPC MDR package?
When specified: approved GA drawing, EN 10204 3.1 material certificates, hydrostatic/pneumatic test records to the applicable test standard, NDE reports required by the ITP, coating records if painted, and the ITP release note. CAD/STEP models and bilingual datasheets are issued after size, class and trim are frozen — they are not generic public downloads.
Which design and test standards apply to the 3/4inch Forged Stainless Steel F304 Socket Welded Swing Check Valve?
Design reference: API 602, ASME B16.34. Face-to-face: ASME B16.10 / ASME B16.11. Pressure test / inspection: API 598 / project ITP. NACE, fire-safe or fugitive-emission clauses are quoted only when the purchase specification requires them.
