Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
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 valve body can be made of carbon steel (WCB) or stainless steel (CF8 or CF8M) as per ASTM A216/A351. Other materials like brass may also be available, but verify with the supplier.
The leakage rate is Class IV–VI, which corresponds to 0.01–0.05% of Cv (IEC 60534-4). This indicates the allowable leakage when the valve is closed. Confirm the specific class for your model.
The response time for a 90% step change is 0.5 to 2.0 seconds (IEC 60534-5). This is a reference value; actual response time may vary based on size and operating conditions.
