Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
8 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.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
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.
