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.
It protects the manifold and connected equipment from damage due to excessive pressure by automatically releasing fluid when pressure exceeds a preset limit.
Nominal diameters range from DN15 to DN50, and set pressure is adjustable from 0.1 to 1.6 MPa. These are reference ranges; confirm exact values for your model.
Body materials include stainless steel (304/316) and brass. The seat is made of PTFE for chemical resistance. Verify material suitability for your application.
Relevant standards include ISO 5208 for leakage, ISO 4126-1 for pressure relief devices, ASTM A351 for body material, ASTM D4894 for PTFE, and ISO 7005 for flanged connections. These are references for verification, not certification.
