Precision Engineered for Critical ApplicationsDesigned according to global standards such as ASME B16.34 and API 6D, the AUDCO (LnT) Lift Type NRV guarantees reliability under demanding industrial operations. Its structure optimizes flow control while preventing backflow, a vital requirement for line integrity in oil, gas, steam, and water applications.
Quality Construction and Versatile MaterialsWith components available in cast iron, cast steel, stainless steel, alloy steel, and bronze, this NRV offers hard-faced seating, spiral wound/compressed fiber gaskets, and renewable discs for enhanced longevity. Metal-to-metal or soft seating options cater to diverse process requirements and fluid types.
Simplified Installation and Flexible ConfigurationFlanged ends conforming to ASME B16.5/BS/DIN standards make the NRV easy to install. Its preferred horizontal mounting, and adaptability for upward-flow vertical installation, ensure seamless integration across varied plant setups and piping networks.
FAQ's of AUDCO (LnT) Make Lift Type NRV:
Q: How is the AUDCO (LnT) Lift Type NRV installed and in which orientation?
A: Installation is straightforward due to the flanged ends as per ASME B16.5/BS/DIN. The NRV operates best in a horizontal position, but it can also be mounted vertically if flow is upward. Always follow the arrow marked on the body for correct flow direction.
Q: What types of media can be handled by this non-return valve?
A: The valve is designed for versatile industrial use, capable of handling water, oil, gas, steam, and other process fluids, making it suitable for pipelines in power plants, refineries, and utility networks.
Q: When should I choose metal-to-metal sealing versus soft seated sealing?
A: Metal-to-metal sealing is recommended for high-temperature and abrasive applications, providing durability and tight shutoff at up to 427C. Soft seated options can be selected for milder conditions where enhanced bubble-tight sealing is required.
Q: Where are the typical applications for this Lift Type NRV?
A: It finds use in industries such as water supply, oil & gas, steam pipelines, and power generation, providing backflow protection in process lines, utility infrastructure, and critical service environments.
Q: What benefits does the renewable seat and disc design offer?
A: The renewable seat and disc streamline maintenance by allowing easy replacement of worn components, thereby extending the valve's service life and reducing downtime for repairs.
Q: How does the valve ensure compliance with industry testing and quality standards?
A: Each valve undergoes rigorous testing in accordance with API 598 and BS 6755 Part-1 standards for pressure integrity and reliability, ensuring high operational safety and consistent performance.
