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 drain valve is available with threaded or socket weld connections, per ISO 228-1. The specific connection type must be matched to the container outlet and piping system. Always verify compatibility with the manufacturer.
The operating temperature range is -20°C to 60°C. Outside this range, seal integrity may fail. Confirm the exact limits for your specific model and application with the supplier.
Seat materials range from EPDM to FKM, per ASTM D2000. EPDM is suitable for water, while FKM is for chemicals. The choice depends on the liquid being handled. Verify material compatibility with the manufacturer.
The leakage rate is specified as Class A, with a range of 0 to 0.1 mL/min. This indicates a tight seal under test conditions. Always verify the leakage class for your specific model and application.
