Benefits of the ball crane
Currently, ball valves are the most common, as they are very convenient and practical, and one of the main advantages of the ball valves, compared to the old traditional cranes, is the lack of need to change the gasket, because the device and the principle of operation of the ball crane is completely different.Inside the ball crane, a metal ball is located, which in one position is open and does not interfere with the movement of water, and when it turns 90 degrees, it completely overlaps the flow of water.
Disadvantages of ball cranes
But such cranes have cons. If the quality of the water is very bad, the ball can stick together. If the crane for a long time does not rotate, especially in the case of using it on hot water, there may be problems with its closure, and sometimes it becomes impossible. Therefore, it is necessary to turn it at least once every two months in order to knock all salt sediment on it.
If the water flowing through the crane contains rust, then when opening and closing the crane, its surface may be damaged by sand and scale, which will lead to the fact that in the closed position the faucet starts to be treated. Also, it may occur from under the gland on medium quality cranes, especially often this happens on heating and hot water. Of course, the crane can be tightened, but it happens that the nut that presses the gland, starts to spin together with the lever and flow the crane does not stop. And on some models, the kranel of the gland is not at all, when the leaks appear, you can simply throw it out and install a new crane in its place.

There is a ball crane and one more minus - it cannot be installed indoors, in which the temperature may drop below 0 degrees, as it can simply break if the water freeze.
How to install a ball crane correctly?
Sequence of necessary actions, when installing a ball valve on the pipe:
1. If you are going to replace the old crane for a new one, then you first need to remove the old, thoroughly clean the threads and then try to wind a new crane. It often happens that after removing the old crane, it turns out that several turns just rotted and, therefore, you need to do thread. When screwing the crane on the pipe, it should be at least four turns.
2. If, after removing the old crane, it can be seen that the thread is in a normal state, then you can safely screw the new crane that at least four revolutions should be cooked. But first you need to drive a scatter with a scatter.
3. If when checking the crane without flax can reach 4-5 revolutions, then it is necessary to wind the flax and finally turn the crane to the pipe for 4-5 revolutions.
4. When installing heating or water supply, you must first set the place where the crane will be installed, then cut off the pipe in this place, cut the thread on it and wind the crane for 4-5 revolutions.
If there are centralized heating and high pressure supply in the system, you need to use cranes made by Bugatti, as they have proven themselves very well. And you do not need to install cranes without a gland, since when there is a leak, it will not be possible to repair.
Ball cranes can be several types:
- Internal thread on both sides;
- Outdoor thread on both sides;
- On the one hand, internal, and with another outdoor;
