Ductile Iron Flange Check Valve, ANSI/ISO Standard, for High Temperature Steam and Water Applications

Ductile Iron Flange Check Valve, ANSI/ISO Standard, for High Temperature Steam and Water Applications

Our flange check valve is specifically engineered to prevent backflow in high-temperature steam and water systems, ensuring unidirectional flow and protecting critical equipment. Constructed from high-strength ductile iron (nodular cast iron), this valve offers exceptional durability and corrosion resistance under demanding conditions. The flange end connection ensures secure, leak-proof installation, while the efficient check mechanism operates with minimal pressure drop. Compliant with ANSI and ISO standards, this valve handles temperatures up to 80°C and is ideal for industrial applications in petroleum, chemical, and power generation sectors. With a 2-year warranty and optional accessories including O-rings and sealing rings, it delivers reliable, long-lasting performance.
