Factory Price Water Meter Brass Check Valve Non Return Horizontal Valve

The water meter check valve only allows water in the water pipe to flow in one direction. When fluid pressure acts in the same direction, the valve disc will open; If the fluid flows in the opposite direction, the valve disc will automatically overlap, cutting off the flow of water and preventing the backflow of tap water. Installing a check valve in front of the water meter can effectively prevent damage to the water meter due to backflow, especially to prevent the backflow phenomenon from causing damage to the internal structure of the water meter, thereby affecting its normal measuring function.

For commercial or industrial users, especially in scenarios with complex systems and high water consumption, it may be necessary to install check valves before and after the water meter. Installing a check valve in front of the water meter can effectively prevent damage to the water meter due to backflow, protect the internal structure of the water meter from damage, and ensure the normal metering function of the water meter. At the same time, it can also help maintain stable system pressure and ensure the accuracy of water meter measurement. Installing a check valve after the water meter can further prevent the backflow of water from the user end into the public water supply system, providing more comprehensive protection for the system.

For household users, the water supply system is relatively simple, so installing it behind the water meter may be more practical. This can effectively prevent the backflow of water from the user end into the public water supply system, protecting the safety of the public water supply system. In some special cases, such as when there may be water backflow in old pipeline systems, or when the water quality at the user end in some high-rise buildings may affect the overall water supply system, installing check valves is particularly important. At this point, a suitable installation location can be selected based on the actual situation to ensure the safety and stability of the water supply system.

Installation precautions

Check appearance and brand: Ensure that the appearance of the check valve is undamaged, the brand is reliable, and meets installation standards.

Conduct strength and sealing tests: Before installation, check valves can undergo strength and sealing tests to ensure their quality is qualified.

Correct installation: Install according to the installation instructions or professional guidance to ensure that the check valve can work properly.
