Technical Specifications

The Athena Axial Flow Check Valve is designed according to API 6D design standards and ASME B16.34 for transporting oil, gas, water, and other fluids under non-return conditions. The valve face-to-face dimensions comply with ASME B16.10, and flanged connections follow ASME B16.5 standards. Materials meet NACE MR0175 requirements, and testing adheres to API 598 standards.

Materials and Construction

The valve body and main parts are available in carbon steel and stainless steel variants, including A352-LCB, A351-CF8, A216-WCB, and A351-CFBM. Key components include:

• Body: One-piece construction for reduced weight, enhanced strength, and ease of maintenance.
• Disc: Designed to reduce operational force and ensure reliable sealing.
• Guiding Parts: Made from stainless steel (SS304, SS316) to ensure durability and low noise operation.
• Spring: Options include SS304, SS316, and Inconel X-750 for corrosion resistance and longevity.
• Sleeve: Stainless steel sleeve protects pump operation.

Design Features

• Axial flow design ensures low noise and smooth operation.
• Spring-assisted disc reduces the force required to open the valve, improving responsiveness.
• Sealing surfaces made from SS304 provide excellent and durable sealing performance.

Dimensions and Pressure Classes

The valve is available in multiple sizes ranging from 50 mm to 500 mm nominal diameter (NPS 2 to 20), supporting pressure classes including 150, 300, 600, 900, 1500, and 2500 psi (PN10 to PN40). Face-to-face lengths and flange patterns (RF, RTJ, BW) conform to ASME standards, with detailed dimensional data provided for each size and class.

Applications and Usage

Suitable for oil, gas, and water transport systems requiring non-return valves to prevent backflow. The valve’s robust design and material selection make it appropriate for harsh environments, including low temperature and corrosive conditions.

Recommendations and Best Practices

• Ensure proper selection of material grade based on the fluid and environmental conditions.
• Follow API and ASME standards for installation and maintenance to guarantee performance and safety.
• Regular inspection and testing per API 598 to maintain valve integrity.

Summary

The Athena Axial Flow Check Valve offers a reliable, low-noise, and maintenance-friendly solution for non-return applications in oil, gas, and water industries. Its compliance with international standards and use of high-quality materials ensure durability and operational efficiency.
