The CR-31A is a cast iron reflux valve of swing check type, engineered as a non-return valve for industrial applications with a higher pressure rating of PN16. It complies with the IS:5312 standard and features a straight pattern body made from Cast Iron IS:210 Gr.FG200, offering robust performance in demanding systems. The valve includes a bolted cover, with options for integral or renewable seats and a renewable disc.
Swing check valves like the CR-31A are designed to prevent reverse flow in pipelines, with their full-bore design ensuring minimal pressure loss. The FG200 cast iron body is a standard grade, providing durability and resistance to wear in typical industrial settings. Flanged ends are manufactured to IS:1538, ensuring seamless integration with compatible piping systems in India and beyond.
This model is ideal for industries such as oil and gas, water distribution, and power generation, where higher pressure ratings are critical. Aps Marines & Logisitics provides a Works Test Certificate with each unit, validating hydrostatic body test pressure at 2.4 MPa and seat test pressure at 1.6 MPa. Buyers should confirm trade terms, including MOQ and lead time, as these are not specified in the listing.

Prior to ordering the CR-31A Cast Iron Reflux Valve, confirm that the PN16 pressure rating aligns with your system’s requirements, particularly if operating under higher pressures. Ensure the flanged ends (IS:1538) match your piping specifications to avoid compatibility issues during installation.
Coordinate with Aps Marines & Logisitics to clarify lead time, Incoterms, and payment terms, as these are not provided in the listing. Given the supplier’s location in New Delhi, factor in transportation logistics, including port access and inland freight costs. Discuss whether the Works Test Certificate suffices or if additional inspections are needed for your project.
Upon delivery, inspect the valve for defects, focusing on the renewable seat and disc, which are critical for long-term performance. Verify that the hydrostatic test pressures (2.4 MPa for body, 1.6 MPa for seat) meet your safety standards. Request material certification for the Cast Iron IS:210 Gr.FG200 to ensure it adheres to industry norms for durability and corrosion resistance.
