Where is the best position to install the fluorine lined check valve?

We know that check valve The purpose of its function is to prevent the backflow of fluids and other media, which can cause air blockage. It is precisely because of its function that its installation cannot be installed arbitrarily, and the installation position is also very particular. So, how should I install it and where should I install it?
The installation position of fluorine lined check valves is mostly chosen to be installed next to the water meter. The backwash rate in this area is relatively small, which can effectively prevent backflow from causing excessive impact on the water meter. Alternatively, they can also be selected at the bends and bends of the medium pipeline and places with large vertical drops, which can effectively prevent water hammer from damaging the pipeline and impacting the water meter. It is worth noting that there is usually an indicator arrow on the fluorine lined check valve, and the direction pointed by this arrow is the flow direction of the pipeline medium. Therefore, it is important to check carefully before installation, otherwise if the direction is reversed, the fluorine lined check valve will not work.
The above are the precautions for correctly selecting the installation position of fluorine lined check valves, hoping to help everyone.
