Most QUALITY Check Valves FOR YOU

The check valve is basically a one-way valve and is also called a non-return valve, it is generally used in pipelines to prevent backflow.
The flow can run freely in one way and in another way the check valve will be closed to protect the piping system from the water hammer. But at the same time, it will also cause pressure loss so in piping design the risk of the water hammer and pressure loss shall be evaluated to select the right valve type.
