How do I install a check valve correctly to ensure it works properly?

The following steps are required to properly install a check valve to ensure that it works properly:

‌Determine the valve location‌:
Select a suitable pipe section as the installation location of the check valve, and ensure that the location is convenient for subsequent operation and maintenance.

‌Prepare the pipe and valve‌:
Make sure the pipe is clean and free of debris and dirt.
Check whether the check valve's model and specification match the pipe diameter and confirm that the valve's maximum pressure and temperature meet the system requirements.

‌Check the valve direction‌:
Check the arrow or mark on the check valve to ensure that its normal flow direction is consistent with the flow direction of the pipe.

‌Install the valve‌:
Could you place the check valve on the pipe and tighten it tightly with appropriate tools (such as a wrench) to ensure that the valve is firmly connected to the pipe to avoid water leakage?

‌Connect the pipe‌:
Use appropriate pipe fittings or threaded connectors to connect the check valve to the pipe to ensure that the connection is tight and there is no water leakage.

‌Test‌:
After installation, test to ensure the normal operation of the check valve. You can open the valve upstream of the pipeline to observe whether the check valve can prevent backflow; close the upstream valve to observe whether the check valve can prevent backflow.

In addition, the following points should be noted during the installation process:
Installation height and direction: The installation height of the check valve and the inlet and outlet directions of the water flow must meet the requirements of the specification.
‌Sealing: When connecting the check valve, pay attention to the flatness and cleanliness of the surface, and apply an appropriate amount of sealant to tighten it to avoid leakage. 4.
‌Maintenance: To ensure that the check valve can operate stably for a long time, regular maintenance and maintenance should be performed after installation.
Following the above steps and precautions can ensure the correct installation and normal operation of the check valve.
