Check valves are mechanical devices used in piping and pipeline systems to prevent back-flow. A check valve allows fluid flow only in one direction that's why it is called a one-way valve or non-return valve Check Valve works on the principle of differential pressure. It means the check valve will only open if the upstream pressure is more than the downstream pressure The only purpose of the check valve is to prevent flow reversal or back-flow and they are available in various sizes, designs, and materials.
