Aluminium Bronze Dual Plate Wafer Type Check Valve

Aluminium Bronze Dual Plate Wafer Type Check Valve is engineered for high-efficiency backflow prevention in systems exposed to corrosive media such as seawater, brine, or chemical solutions. With a dual-plate design and aluminium bronze body, this valve combines strength, compact size, and excellent resistance to corrosion.

The valve features two spring-loaded plates that open under forward flow and close rapidly upon flow reversal. This quick response prevents back pressure damage and helps maintain system stability. The aluminium bronze dual plate wafer type check valve offers a low-pressure drop and quiet operation, minimizing water hammer in sensitive pipelines.

Its wafer-type construction allows easy installation between standard flanges, saving space and weight without sacrificing sealing reliability. Ideal for shipbuilding, desalination plants, offshore platforms, and industrial water systems, this check valve supports both horizontal and vertical upward flow installation.

All valves are tested according to API 594 and EN 12334 standards and are available in a variety of sizes and pressure ratings. The aluminium bronze construction ensures long service life even in harsh environments.

Choose the Aluminium Bronze Dual Plate Wafer Type Check Valve for durable, compact, and corrosion-resistant flow control.

Aluminium Bronze Dual Plate Wafer Type Check Valve Material:

Body: ALUMINIUM BRONZE
