Our cast iron non-return valves are engineered to deliver reliable backflow prevention in water and wastewater pipeline systems. Manufactured from high-grade cast iron (IS:210 FG 200) with thick black bitumen coating (≥200 µm), these valves feature hinge-mounted swing disc mechanisms in single-door (DN 50-600 mm) or multi-door (DN 700-1500 mm) configurations. The corrosion-resistant construction combined with renewable seating materials including gunmetal, bronze rings, or rubber (5-10 mm thickness) ensures tight shut-off and extended service life even in demanding operational conditions.

These valves serve critical functions across multiple industries including municipal water distribution, industrial processing, agricultural irrigation, and wastewater management. Municipal authorities rely on them for protecting drinking water supplies from contamination, while industrial facilities utilize them in cooling systems, process water lines, and effluent discharge systems. Irrigation networks benefit from their reliable operation in water distribution, and fire protection systems depend on their fail-safe performance to maintain water pressure and flow direction during emergency operations.

The business value of these non-return valves lies in their maintenance-free operation, long-term reliability, and cost-effective performance. Designed to withstand pressure ratings of PN1.0/PN1.6 bar (100-160 kPa) and hydraulic test pressures of 1.5×PN for body and 1.1×PN for seat, they provide exceptional value through reduced downtime and minimal maintenance requirements. The versatile installation capability in horizontal or vertical orientations (0°-90°) combined with optional accessories like external bypass or dashpot arrangements makes them adaptable to various system requirements while ensuring consistent performance.
