Check valves are used as one-way or non-return valves in almost every industrial application. Check valves are simple devices that serve an important purpose by preventing reverse flows and thus preventing damage and ensuring efficient operations. Water hammer can be caused by reverse flow. Check valves are used to stop the flow of gas, fluid, and air in the event of a brake failure.

Check valves are installed in water systems to prevent contaminated water from flowing back into clean water supply lines. There are numerous types of check valves that use a variety of materials such as metal, polymers, and rubber and have a wide range of potential applications.

Advantages of check valve:

  • Protect pumps and compressor equipment from backflow damage.
  • It reduces downtime and production losses which is caused by unsuitable valve failure.
  • Water hammer is greatly reduced using check valves.
  • It has low maintenance cost.
