Check valve how it works
WebA check valve works based on the principle of the pressure difference between two sides of the valve. When the pressure on the inlet side is greater than on the outlet side, the valve opens, and fluid flows through it. Conversely, when the pressure on the outlet side is higher, the valve closes and prevents backflow. WebApr 30, 2024 · Generally simple devices, check valves perform a vital function by preventing reverse flows and damage, and ensuring efficient operations. Reverse flow can, for example, result in water hammer. This phenomenon can see repeated extreme pressure surges in connected pipework, valves and pumps that may fatally damage or rupture the …
