The Cast Steel Flange Concentric Disc Butterfly Valve is a quarter-turn flow control device constructed from cast steel, designed for high-pressure industrial systems. It features a concentric disc alignment that minimizes turbulence and ensures consistent sealing under varying flow conditions. The valve has a flanged connection compatible with ANSI and DIN standards, and is available in nominal sizes ranging from DN50 to DN600 based on industry norms.
Cast steel construction provides durability in aggressive environments, with typical material grades such as WCB or WC6 meeting ASTM A216 standards. The disc is often coated with EPDM or NBR elastomers for corrosion resistance, and the stem is typically stainless steel 304 or 316. These materials are standard for valves handling water, steam, oil, and mild chemicals, though exact composition is not confirmed by the supplier.
This valve is commonly used in water treatment plants, oil and gas pipelines, and chemical processing units where reliable shut-off and low-pressure drop are critical. Buyers in power generation, municipal infrastructure, and industrial manufacturing sectors source this valve for retrofitting or new installations. Trade terms are typically FOB China port with standard carton or wooden crate packaging. Minimum order quantities and lead times must be confirmed directly with the supplier.

Before ordering, verify the exact material grade of the valve body and disc, the type of elastomer used for the seat, and whether the valve has been tested for pressure integrity and leakage. Confirm the supplier can provide a material test report (MTR) for the cast steel and seal components. Do not rely on generic claims of 'durability' or 'reliability' without documented proof.
Logistics are typically handled via FOB China port, with standard packaging in wooden crates for valves over DN150. Lead times are not stated but commonly range from 4 to 8 weeks for production and shipment. Payment terms are usually T/T in advance or LC at sight. Buyers must confirm Incoterms, insurance coverage, and export documentation requirements with the supplier before payment.
Upon delivery, inspect the valve for surface defects, proper labeling, and intact packaging. Perform a visual check of the disc alignment and stem movement. Conduct a hydrostatic test at 1.5x working pressure if possible. Request a certificate of conformity, material test report, and packing list. If the valve is for critical service, arrange for third-party inspection prior to shipment.
