The CR-31 is a cast iron reflux valve of swing check type, designed as a non-return valve for industrial pipelines. It carries a pressure rating of PN10 and adheres to the IS:5312 product standard, with a straight pattern body manufactured from Cast Iron IS:210 Gr.FG200. The valve features a bolted cover, integral or renewable seat, and a renewable disc, ensuring durability and ease of maintenance in high-flow systems.
Swing check valves like the CR-31 are typically used to prevent backflow in water, wastewater, and process lines, where their full-bore design minimises pressure drop. The body material FG200 is a standard grade of grey cast iron, known for its strength and corrosion resistance in typical industrial environments. Flanged ends conform to IS:1538, a common Indian standard for pipe flanges, ensuring compatibility with regional piping networks.
This valve is suitable for buyers in water treatment plants, chemical processing, and HVAC systems seeking a reliable non-return solution. Aps Marines & Logisitics supplies it with a Works Test Certificate, confirming hydrostatic body test pressure at 1.5 MPa and seat test pressure at 1.0 MPa. Buyers should confirm MOQ, lead time, and incoterms directly with the supplier, as these are not specified in the listing.

Before ordering the CR-31 Cast Iron Reflux Valve, verify the exact pressure and temperature requirements of your system to ensure compatibility with the PN10 rating and cast iron material. Confirm that the valve’s flanged ends match your piping system’s specifications, particularly the IS:1538 standard for flanges.
Discuss logistics directly with Aps Marines & Logisitics, including lead time, Incoterms, and preferred payment methods. As the supplier is based in New Delhi, consider port proximity and inland transportation costs. Clarify whether the Works Test Certificate is sufficient for your quality control needs or if additional third-party inspections are required.
For quality checks, inspect the valve’s body and renewable components for defects upon delivery. Ensure the hydrostatic test pressures (1.5 MPa for body, 1.0 MPa for seat) meet your project’s safety standards. Request documentation for material traceability, especially for the Cast Iron IS:210 Gr.FG200, to confirm compliance with industry norms.
