Bronze Flange Check Valve

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:

1. Material: Made from bronze (e.g., ASTM B62 or UNS C83600), offering excellent corrosion resistance, especially in water, oil, and non-corrosive fluid systems.

2. 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.

3. Flanged Ends: Equipped with flanged ends for easy installation and secure connection to flanged piping systems.

4. Pressure Rating: Suitable for moderate pressure applications, with pressure ratings defined by standards like ANSI or ASME.

5. Temperature Range: Capable of operating in a wide temperature range, depending on the seat material and application.

6. Sealing: Uses metal-to-metal seating or soft seats (e.g., rubber or PTFE) for tight sealing and durability.

7. Automatic Operation: The disc operates automatically based on flow direction, requiring no external power or manual intervention.

8. Compact and Lightweight: Bronze construction makes the valve lightweight and easy to handle.

Advantages:

1. Corrosion Resistance: Bronze offers excellent resistance to corrosion, making it ideal for water and non-corrosive fluid systems.

2. Backflow Prevention: Effectively prevents reverse flow, protecting equipment and pipelines.

3. Easy Installation: Flanged ends allow for quick and secure installation in piping systems.

4. Automatic Operation: No external power or manual intervention is required for operation.

5. Durability: Bronze construction ensures long service life, even in demanding environments.

6. Lightweight: Easier to handle and install compared to valves made from heavier materials like cast iron or steel.

Considerations:

1. Orientation: Must be installed in the correct orientation (horizontal or vertical) to ensure proper operation.

2. Disc Movement: The swinging disc may cause water hammer in high-pressure systems, requiring additional measures (e.g., dampers or slow-closing mechanisms).

3. Pressure Limitations: Suitable for moderate pressure applications; not ideal for extremely high-pressure systems.

4. Material Compatibility: Bronze is not suitable for highly corrosive or acidic fluids.
