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