The Kirloskar Reflux Valve is based on a simple swing-type design. The disc is hinged at the top, allowing it to swing open under the forward flow of water. When the flow reverses, the disc swings back into a closed position, sealing against the seat to prevent backflow. This mechanism requires no manual intervention or external power source and operates solely on the pressure difference in the pipeline.

This valve is ideal for water and wastewater management, offering a cost-effective solution to protect critical systems from backflow damage.
