China Dual Plate Flanged Check Valve Manufacturers, Suppliers & Factory - API 598 Compliant

Double Plate Flange Check Valve is designed for efficient backflow prevention in industrial piping systems. With a dual-plate structure and flange-end connection, this check valve combines fast response, reliable sealing, and ease of installation. It is widely used in water supply, wastewater treatment, petrochemical, power generation, and HVAC systems.

The valve body is typically made from ductile iron, cast steel, or stainless steel, and can be paired with EPDM, NBR, or metal seats depending on the media and operating temperature. Its corrosion-resistant coating ensures durability in harsh environments, including marine, chemical, and industrial applications.

Designed with flanged ends conforming to DIN, ANSI, or JIS standards, the double plate flange check valve allows for secure mounting between pipeline flanges and is easy to remove for inspection or replacement. The compact construction saves space, while the non-slam closing action minimizes water hammer and vibration within the pipeline.

This valve supports both horizontal and vertical (upward flow) installations, offering flexibility across a wide range of engineering systems. It is available in pressure classes from PN10 to PN40 and sizes ranging from DN50 to DN600 or more, meeting international standards such as API 594.
