Import Check Valve — Buy in Bulk from Supplier in China

This Duo-disc Wafer Check Valve is engineered for backflow prevention in industrial systems, featuring a dual-disc design that minimises pressure loss while maximising flow efficiency. The compact wafer-style body fits between standard flanges for quick installation, eliminating the need for additional piping modifications. The valve is constructed from durable materials suited to harsh environments, including water treatment, chemical processing and HVAC applications.

The dual-disc mechanism reduces hysteresis and closes rapidly under reverse flow, preventing water hammer and system damage. Typical materials for such valves include carbon steel, stainless steel (e.g., ASTM A351 CF8M for corrosion resistance) and ductile iron, with pressure ratings often spanning PN10 to PN40 or Class 150 to Class 300. The wafer design conforms to standard face-to-face dimensions per ISO 5752 or ASME B16.10, ensuring compatibility with most industrial flange systems.

Common buyers include municipal water utilities, petrochemical plants and commercial building contractors who require reliable flow control in pipelines. The valve’s low maintenance needs and long service life make it cost-effective for bulk installations. For trade terms, confirm packaging (commonly wooden crates or cartons), lead time and Incoterms directly with the supplier, as these are not specified in the listing.
