Ball valves are one of the types of valves. The role of the locking element in structures of this type is played by a metal ball. The devices have a long service life and do not require regular maintenance.
The main distinguishing feature is the minimum time required to shut off water or gas. And due to the small overall dimensions, they are installed in places where the use of standard valves is impossible due to limited space.

Shut-off ball valves are reliable and easy to operate. As well as:
Ball valves have few disadvantages:
Also, the disadvantages include the occurrence of water hammer in the heating system when the tap is quickly opened.
Since there are a lot of Chinese products in stores, both high-quality and outright fakes, the choice of valves should be approached responsibly.
Before buying, it is worth determining the diameter of the pipe on which the device will be installed and the type of threaded connection (internal or external).
High-quality devices are supplied complete with a passport, which indicates: warranty period, product number, material and installation instructions. Savings on shut-off valves can lead to significantly higher repair costs, for example, in the event of a ball valve failure.
The ball valve must turn freely enough.If you need to make significant efforts to rotate, it is better to refuse the purchase.
Also, do not buy products with a handle made of plastic. With frequent use, over time, the handle will begin to scroll.
Another important point is the indicators of conditional and working pressure. The first one should be higher. If equal values are indicated in the technical specifications, serious damage is possible during operation in the event of a sharp jump in pressure in the water supply system.
Also worth paying attention to:
The metal should have a uniform luster, without streaks and sagging. All parts are symmetrical, the coating is without cracks and chips, the same wall thickness of the case. Marking is clear, with easily distinguishable and readable letters. A sign of a fake is a dull or cloudy outer coating.
Brass - the most common and affordable. Ideally, the brass marking is CW617N. Such products are heavy in weight, the threaded walls are thicker. It is also worth noting that faucets made of silumin, an alloy of aluminum and silicon, are much cheaper than brass counterparts. But at the same time they are characterized by increased fragility. From exposure to hot water quickly destroyed. They are used as shut-off valves for systems that do not provide for high pressure and only for cold water. You can determine the silumin device by its appearance - poor coverage, uneven seams. Also, silumin products are distinguished by a characteristic silver color.
Many people advise this method of checking ball valves: remove the top nickel layer with any sharp object. The problem is that this can only be done after the purchase. After all, it is unlikely that someone in the store will allow you to scratch and spoil the goods.Therefore, you need to purchase valves from trusted sellers or directly from official representatives of the manufacturer.
Steel - made of carbon steel, they are distinguished by high performance, resistance to mechanical stress. For the price - more expensive than brass.
Depending on the purpose for which the crane is purchased, pay attention to the manufacturer's recommendations:
Although recently, experts recommend replacing cast-iron fittings with steel. Since at a higher cost, cast iron products in terms of technical characteristics are no different from steel counterparts.
Should be perfectly smooth, without scratches and damage. High-quality gates are made of brass with subsequent chrome plating.
A fake is easy to recognize by the characteristic matte color of the coating. You can also check the metal with a magnet. If it attracts, it means that the manufacturer saved money and used electrical steel, which is susceptible to corrosion. As a result of constant contact with water, the valve will quickly rust and fail.
To buy a device that will last a long time, sometimes it is not enough just to come to the store and purchase the first model that comes across. First, you should study all the ratings and reviews.This review is compiled on the basis of expert opinions in the field of shut-off equipment installation, as well as direct users who have already used ball valves from leading companies in their experience.
