The flanged lift check valve is a type of valve that allows liquid and gas flow in only one direction. It is used in the system to prevent backflow. When the flow direction reverses, it automatically closes to stop the backflow. This feature helps protect piping and pump systems.

The disc inside the valve body is lifted when the flow starts. When the flow stops, the disc closes onto the seating surface due to its own weight and system pressure. This design prevents backflow. Thanks to the flanged connection, it can be easily integrated into systems.

Where Are Flanged Lift Check Valves Used?

Flanged lift check valves are generally preferred in high-pressure lines. They are used to ensure safe flow in industrial liquid transfer systems. They are also commonly used in water treatment plants, fire protection systems, and heating-cooling lines.

It is preferred in the petrochemical, power generation, and chemical industries due to its long-lasting performance. Additionally, when used on pump discharge lines, it enhances system safety against backflow. It provides an ideal solution for protecting pumps and other equipment in piping systems.
