A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory data, common pressure ratings are PN16 to PN40, which correspond to ASME Class 150 to 600. However, the exact rating depends on the valve size, body material, and design. Always confirm the pressure rating with the manufacturer for your specific model.
Body materials include cast carbon steel (WCB), cast stainless steel (CF8, CF8M), and forged stainless steel (F304/F316). Seats are typically made of PTFE, RPTFE, or PEEK. For corrosive services, alloys like Alloy 20 or Hastelloy C may be used. Material selection depends on the media and operating conditions.
Common standards include API 608, ISO 17292, ASME B16.34, ASME B16.10, ASME B16.5, EN 12516-1, and GB/T 12237. These cover design, dimensions, pressure-temperature ratings, and testing. Compliance with these standards should be verified with the manufacturer.
Selection involves specifying nominal diameter (DN), pressure rating, end connections, body and seat materials, and required features like fire-safe design or anti-static devices. Consider the media, temperature, and flow requirements. Always consult the manufacturer's data and verify that the valve meets your system's specifications.
