Introduction to Check Valves
Check valves, also known as non - return valves or one - way valves, are essential components in fluid systems. Their primary function is to allow fluid (liquid or gas) to flow in one direction only and prevent backflow. This is crucial in many applications, such as water supply systems, oil and gas pipelines, chemical processing plants, and power generation facilities. By preventing reverse flow, check valves protect pumps, compressors, and other equipment from damage, maintain system pressure, and ensure the proper operation of the overall fluid system.
