Never buy ball valves without checking with my recommendation

All craftsmen are well aware of the low physical parameters of the strength of silumin - the most used stainless alloy in low-quality Chinese products. Even with minor static loads, water fittings crack after a few months; the consequences of such situations are very unpleasant. In the best case, the tap will break during dismantling and you will have to remove the threaded part from the internal thread. In the worst case, there will be expensive unscheduled repairs of premises due to flooding. There is a simple way to check the quality of ball valves.

What you need to have

The permanent magnet is small in size and should fit inside the faucet.

Verification technology

Slightly wiser manufacturers prove to consumers that the faucet body is not made of silumin. For this purpose, threads with open turning areas are shown; the inner surface of the body is also yellow. But they continue to try to reduce production costs as much as possible and use lower quality, but cheaper metals in the manufacture of individual parts.

The main sealing element of the faucet is a special ball with a hole that rotates in the body. Unscrupulous Chinese manufacturers use ordinary ferrous metals, rather than stainless alloys, to make the ball. The surfaces are chromed, become shiny and beautiful, and at first the design works great. Over time, the protective anti-corrosion coating loses its integrity, the ball becomes covered with rust, and the valve jams in the open or closed position.

To determine the material of the ball, use a small magnet, lower it into the tap, and turn the body over. If the magnet sticks and does not fall out, you have a low-quality faucet. A magnet is not attracted to bronze or stainless steel.
When choosing fittings, be sure to pay attention that all elements of the devices are made of bronze or brass, and not silumin or ferrous metals.

Conclusion

You should not think that all Chinese products are of low quality; this country is far ahead of us in terms of technical development. Low-quality products come to us due to the fault of domestic traders who buy various counterfeits at the lowest price.
Valves with metal ball valves can only be used for air pipelines; for all other options it is strongly recommended to purchase high-quality and durable fittings.
