Introduction to Check Valves
A check valve, also known as a non – return valve or one – way valve, is a mechanical device that allows fluid (liquid or gas) to flow through it in only one direction. Its primary function is to prevent the backflow of the fluid, which is crucial in many industrial applications to ensure system safety, efficiency, and proper operation. Check valves are widely used in various industries such as water treatment, oil and gas, chemical, and power generation. They come in different types, including swing check valves, lift check valves, ball check valves, and diaphragm check valves, each suitable for different flow rates, pressures, and media. Check Valve
