A Bronze Flange Check Valve is a type of check valve designed to allow fluid flow in one direction while preventing backflow in the opposite direction. It is constructed from bronze, a durable and corrosion-resistant material, making it ideal for use in water, oil, and other non-corrosive fluid systems. The valve features flanged ends, which allow for easy installation and secure attachment to piping systems using bolts. Its automatic operation ensures reliable backflow prevention without the need for external power or manual intervention.

Product Details:
Size: 18”
Pressure: 150LB
Material: C95800
End Connection: Flange
Design & Manufacture Std.: API 6D, BS 1868, API 594, ASME B16.34
Test Standard: ISO5208, API 6D, BS 6755
Key Features:
-
Material: Made from bronze (e.g., ASTM B62 or UNS C83600), offering excellent corrosion resistance, especially in water, oil, and non-corrosive fluid systems.
-
Swing Disc Design: Features a hinged disc that swings open with forward flow and closes automatically by gravity or backpressure when the flow stops or reverses.
-
Flanged Ends: Equipped with flanged ends for easy installation and secure connection to flanged piping systems.
-
Pressure Rating: Suitable for moderate pressure applications, with pressure ratings defined by standards like ANSI or ASME.
-
Temperature Range: Capable of operating in a wide temperature range, depending on the seat material and application.
-
Sealing: Uses metal-to-metal seating or soft seats (e.g., rubber or PTFE) for tight sealing and durability.
-
Automatic Operation: The disc operates automatically based on flow direction, requiring no external power or manual intervention.
-
Compact and Lightweight: Bronze construction makes the valve lightweight and easy to handle.
Advantages:
-
Corrosion Resistance: Bronze offers excellent resistance to corrosion, making it ideal for water and non-corrosive fluid systems.
-
Backflow Prevention: Effectively prevents reverse flow, protecting equipment and pipelines.
-
Easy Installation: Flanged ends allow for quick and secure installation in piping systems.
-
Automatic Operation: No external power or manual intervention is required for operation.
-
Durability: Bronze construction ensures long service life, even in demanding environments.
-
Lightweight: Easier to handle and install compared to valves made from heavier materials like cast iron or steel.
Considerations:
-
Orientation: Must be installed in the correct orientation (horizontal or vertical) to ensure proper operation.
-
Disc Movement: The swinging disc may cause water hammer in high-pressure systems, requiring additional measures (e.g., dampers or slow-closing mechanisms).
-
Pressure Limitations: Suitable for moderate pressure applications; not ideal for extremely high-pressure systems.
-
Material Compatibility: Bronze is not suitable for highly corrosive or acidic fluids.
