Basic Concepts of Check Valves

A check valve, also known as a non-return valve, is a mechanical device that allows fluid to flow through it in only one direction. It operates using a simple mechanism where a disc or ball is lifted off its seat by the pressure of the fluid flowing in the correct direction. When the flow reverses, the disc or ball returns to its seat, blocking the flow and preventing backflow. Check valves are commonly used in various fluid systems, including water, gas, and oil, to ensure that the fluid moves in the desired direction and to protect equipment from damage caused by reverse flow ².
