C.I. Reflux N.R.V.​

The C.I. Reflux N.R.V.​ (Non-Return Valve) is a specialized valve designed to prevent backflow in piping systems. Here’s a detailed description of its features, specifications, and applications:

  1. Material: Constructed from cast iron (C.I.), providing durability and resistance to corrosion, suitable for various environments.

  2. Size Range: Available in sizes ranging from 2 inches to 8 inches, offering flexibility to accommodate different pipe diameters and flow rates.

  3. Product Standard: Compliant with API 594 standards, ensuring quality, reliability, and compatibility with industry requirements.

  4. Design: Features a dual-disc design, making it a more efficient alternative to traditional swing check valves. The wafer type design, combined with spring-loaded action, enhances performance and reliability.

  5. Test Pressure:

    • Body: Tested up to 348 PSIG (Pounds per Square Inch Gauge) hydrostatic pressure.
    • Seat: Tested up to 232 PSIG hydrostatic pressure, with an additional low-pressure test at 15 PSIG hydrostatic pressure.

  6. Max. Working Temperature: Capable of operating at temperatures up to 80°C (176°F), suitable for a wide range of applications.

  7. Design Features:

    • Integrally molded liner for enhanced sealing and durability.
    • Two independent seats ensure consistent sealing even in uneven flow conditions.
    • Suitable for clamping between flanges according to ANSI B-16.1 Class-125 standards.
    • Lighter in weight and smaller in size compared to conventional swing check valves, offering space-saving benefits.
    • Uniform stress distribution due to the cylindrical design of the body, enhancing structural integrity.
    • Low cracking pressure and virtually non-existent water hammer, improving system performance and longevity.
    • Can be installed either vertically or horizontally, providing flexibility in system design and layout.

  8. Certification: Works Test Certificate can be issued upon request, ensuring compliance with quality standards and specifications.

  9. Applications: Ideal for use in water and air systems, including but not limited to:

    • Water supply networks
    • Wastewater treatment plants
    • Industrial air systems
    • HVAC (Heating, Ventilation, and Air Conditioning) systems

The C.I. Reflux N.R.V.​ offers a reliable and efficient solution for preventing backflow in piping systems, with its robust construction, dual-disc design, and versatile applications across various industries.
