Cast Iron Horizontal Lift Check ( Non-Return ) Valve - IBR Approved

Feed Check Valves are critical safety and control components used in boiler and heater process pipelines. Their primary function is to regulate and control the flow of feedwater into the boiler drum or heater coil, while preventing backflow from the boiler to the feed line. These valves are designed to withstand high pressure and temperature conditions, ensuring safe and efficient boiler operation. Typically mounted at the boiler shell, the valve automatically prevents reverse flow when the pump is stopped or pressure falls, thus protecting pumps, piping, and the boiler itself. Constructed from robust materials such as cast steel, forged steel, or alloy steels, feed check valves ensure long service life under thermal and pressure cycling. They are available in bolted bonnet or pressure seal types, with options for swing check or lift check mechanisms depending on service requirements. Precision-machined seating surfaces and guided disc arrangements guarantee leak-tight sealing and reliable operation under varying load conditions. Feed check valves are indispensable in modern boiler systems, contributing to system safety, process reliability, and energy efficiency.
