Check Valve

Check valve—Check valves can prevent fluid backflow automatically. It is also known as non-return valve. Usually, fluid pressure opens the valve disc. Fluid flows from the inlet side to the outlet side. When the inlet pressure is lower than the outlet pressure, the valve disc closes the passage automatically by fluid pressure and its own weight. It stops the reverse flow of fluid. You need to notice the installation direction.( Arrow marks are printed on the valve body).
