Import A216 Wcb Cast Carbon Steel Swing Check Valve — Buy in Bulk from Supplier in India

The A216 WCB Cast Carbon Steel Swing Check Valve from SQK Valves Fittings & Automation Private Limited is engineered for backflow prevention in industrial pipelines, featuring a swing disc mechanism that closes automatically under reverse flow. This valve is constructed from A216 WCB cast carbon steel, a material selected for its tensile strength of 485 MPa typical and resistance to corrosion in moderate environments. The flanged design supports pressures up to 1500 PSI, with sizes available from 2 inches to 12 inches to match pipeline diameters.

Swing check valves are standard in water treatment, oil and gas, and chemical processing due to their low pressure drop and self-acting closure. The WCB grade is a cast carbon steel variant with a typical carbon content of 0.25-0.30%, offering a balance of weldability and durability. The valve’s body and disc are typically machined to a standard surface finish of 125-250 Ra to reduce turbulence, while the hinge pin is hardened for extended service life under cyclic loading.

Municipal water systems use these valves to protect pumps from backflow, while oil refineries deploy them in transfer lines for crude and refined products. Buyers should confirm flanged connection standards (ASME B16.5 typical), as well as the valve’s suitability for the fluid’s temperature range, which for WCB is typically -29°C to 425°C. Packaging is industrial-grade, with wooden crates or pallets to prevent damage during transit. Terms such as FOB or CIF are negotiable, and MOQs are flexible to accommodate bulk orders.
