Get tips and insights about check valves and how they work
Check valves, non-return or one-way valves, allow liquid or air to flow in only one direction. Manufacturers make them in a wide range of sizes and types. Tremendous varieties of applications use them to prevent costly or even dangerous backflow.
Even though check valves are widely used for everyday applications, the how and why of check valves and their different designs is not always well understood. Here is some additional information about check valves from the ISM blog:
