Function: Classification: 1. Swing Check Valve: The disc rotates around the seat axis, offering lower flow resistance compared to lift check valves. It’s suitable for low-flow applications but not recommended for pulsating flows. These valves come in single-disc, double-disc, or multi-disc versions, depending on the size and flow requirements. 2. Lift Check Valve: The disc moves vertically within the body. These are typically installed in horizontal pipelines and are often used in high-pressure, small-diameter systems. The disc is guided by a sleeve to ensure smooth movement. They are similar in design to globe valves and offer better sealing performance under certain conditions. Check valves are essential components in piping systems, allowing media to flow in one direction only. Also known as one-way valves, reflux valves, or back-pressure valves, they play a crucial role in maintaining system integrity and safety.

A check valve is an automatic valve designed to prevent the reverse flow of media, which helps protect pumps and motors from damage due to backflow. It can also be used to release pressure in pipelines where the pressure may exceed system limits. This type of valve ensures safe and efficient operation in various fluid systems.
