Versatile, High-Performance DesignThe AUDCO (LnT) Swing Check Valve boasts a full bore design for optimal flow capacity, coupled with a rugged swing-type construction and bolted top cover. Its epoxy-coated or project-specified finish enhances corrosion resistance, ensuring longevity and reliable performance in demanding industrial environments. This valve is suitable for both horizontal and vertical installations, offering flexibility to match site requirements.
Comprehensive Standards and CertificationsEngineered in adherence to stringent international standards-ANSI/ASME B16.5, B16.47, API 6D, ASME B16.10, and API 598-the valve maintains product integrity across pressure classes (PN16, PN25, PN40, Class 150-2500 ASME). Optional certifications such as PED and ISO9001 are available, underscoring commitment to global quality benchmarks and safety protocols.
Reliable, Low-Maintenance OperationThis swing check valve is designed for extended service life with minimal upkeep, thanks to self-actuating, non-return operation and robust materials. The single swing disc ensures quick response and effective backflow prevention, while high-quality gaskets and seat materials (metallic or soft) provide superior sealing for a wide range of liquids, gases, and steam.
FAQ's of AUDCO (LnT) Make Swing Check Valve:
Q: How does the AUDCO Swing Check Valve prevent backflow in a pipeline?
A: The valve employs a swing-type disc mechanism that allows fluid to flow in one direction only. If the flow reverses, the disc closes automatically, preventing any backflow and safeguarding your system.
Q: What are the available end connection and design standards for this valve?
A: This swing check valve is designed and manufactured following ANSI/ASME B16.5 or B16.47 for flanged connections and meets API 6D or BS EN ISO 14341 for design, ensuring interoperability and compliance with international piping practices.
Q: Where can the AUDCO Swing Check Valve be installed within an industrial system?
A: The valve can be installed in both horizontal and vertical pipeline orientations, making it suitable for a wide range of process systems including water, oil & gas, chemical, steam, and general process lines.
Q: What pressure and temperature ranges does this valve support?
A: Depending on the material and class, the valve accommodates pressure ratings from PN16 to PN40 (or ASME Class 150-2500), and operates efficiently in temperatures from -10C to 220C.
Q: How is the valve tested for quality and reliability?
A: Each valve undergoes rigorous hydrostatic and seat leakage testing in accordance with API 598 and ASME standards to ensure safe and leak-free operation in demanding industrial settings.
Q: What are the main benefits of using this swing check valve in a process application?
A: The key benefits include high flow capacity, tight and reliable sealing, self-actuating non-return operation, long service life with low maintenance, and suitability for a broad range of media and applications.
