Audco API 602 Forged Steel Check Valves refer to a series of check valves designed and manufactured by Audco, a well-known brand in the valve industry. These check valves are specifically constructed using forged steel, which adds strength and durability to the valve, making them suitable for various industrial applications. Here are some key features and characteristics associated with Audco Forged Steel Check Valves:

1. Forged Construction: These check valves are made through a forging process, wherein heated metal is shaped and compressed to form the desired valve components. Forged steel enhances the strength and integrity of the valve, making it suitable for high-pressure and high-temperature applications.

2. Swing Check Design: Check valves, including those manufactured by Audco, often employ a swing check design. This means that the valve has a disc (flapper) that swings on a hinge or trunnion. The disc swings open to allow forward flow and swings closed to prevent backflow.

3. Pressure Ratings: Audco Forged Steel Check Valves are designed to handle various pressure ratings, ranging from standard to high-pressure applications. The pressure class is typically indicated in units such as Class 150, 300, 600, 800, 900, 1500, and 2500.

4. End Connections: These valves come with different end connection options to suit the requirements of various piping systems. Common end connections include threaded, socket-weld, and flanged connections.

5. Material: The forged steel used in the construction of these check valves is often selected based on factors such as the type of fluid, pressure, and temperature conditions. Common materials include carbon steel, stainless steel, and alloy steel.

6. API Standards: Depending on the specific model, Audco Forged Steel Check Valves may comply with industry standards such as those set by the American Petroleum Institute (API), ensuring that the valves meet rigorous design and testing criteria.

7. Size Range: These valves are available in various sizes to accommodate different pipe diameters and flow rates.

8. Applications: Audco Forged Steel Check Valves are suitable for applications where preventing backflow is crucial, such as in oil and gas, petrochemical, power generation, and other industrial processes.

As with any valve selection, it’s important to consider the specific requirements of the application, including pressure, temperature, and fluid characteristics. Always refer to the manufacturer’s documentation and guidelines for accurate information on a particular Audco Forged Steel Check Valve model.
