Wholesale Price Water Meter Brass Pipe Fittings with Non-Return Valve with ISO 4064 Standard

The water meter check valve can effectively prevent water backflow, thereby avoiding the water meter from idling due to water flow backflow and ensuring the accuracy of measurement. In addition, it can also reduce the frequency of water meter rotation, effectively solving the problem of water meter rotation caused by pressure fluctuations. When the pressure inside the water pipe increases and the water is compressed, the water meter will rotate in the positive direction; When the pressure drops, the check valve closes and the water meter does not rotate. Therefore, as long as the pressure does not exceed the pressure setting of the check valve, the water meter will not rotate again, greatly controlling the frequency of rotation of the water meter.

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.

Water meter check valve, also known as check valve or one-way check valve, is an automatic valve installed near the water meter to prevent water flow from reversing. The water meter check valve can ensure that water in the pipeline can only flow in one direction, effectively preventing the backflow of water flow. By preventing backflow of water flow, the water meter check valve can reduce the self rotation phenomenon caused by the reverse flow of water flow, thereby ensuring the accuracy of water meter measurement. Preventing backflow of water flow can also prevent damage to pipeline equipment caused by reverse impact of water flow, extending the service life of the equipment.

The check valve installed behind the water meter can effectively prevent the backflow of water flow from the user end into the public water supply system, which is extremely important for protecting the safety of the public water supply system. Especially in high-rise buildings, the water quality at the user end may have an impact on the overall water supply system, and check valves can effectively prevent this situation from occurring.
