"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. " - How does a flow check valve work
