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.
The reference operating pressure range is 1.0–1.6 MPa. Always verify the exact range for your specific model with the manufacturer.
The materials on file include stainless steel, brass, carbon steel, and engineering plastics. The body material is specified as gray cast iron HT250 per ASTM A48, with optional stainless steel trim. Confirm material suitability for your fluid and environment.
The listed standards include ISO 5208 for pressure testing and leakage, and ISO 228-1 for port connections (BSPP). These are reference standards for verification; compliance must be confirmed with the manufacturer.
Signs of wear or failure include increased seat leakage, slower response time, or abnormal noise during operation. If you observe these, inspect seals and valve elements, and replace worn parts as needed.
