Introduction to Check Valves
Check valves, also known as non - return valves or one - way valves, are essential components in fluid control systems. Their primary function is to allow the flow of fluid (liquid or gas) in one direction only and prevent backflow. This is crucial in many applications, such as in pipelines to protect pumps from damage due to reverse flow, in heating and cooling systems to maintain proper circulation, and in various industrial processes to ensure the integrity of the fluid flow path. Check valves come in different types, including swing check valves, lift check valves, ball check valves, and diaphragm check valves, each with its own unique working principle and application scenarios.
