A Detailed Overview of Check Valve Types and Their Applications

Check valves are critical components that prevent backflow of fluids, ensuring the stable operation of industrial and residential fluid systems. Major types include swing check valves (single-disc, double-disc, and multi-disc) and globe check valves (vertical and horizontal), which are suitable for various pipe sizes and flow rates. Materials such as cast iron, cast steel, and stainless steel offer a wide range of options to meet requirements for corrosion resistance, pressure, and temperature.
