Ball cocks
Currently, valve and ball types are most widely used. Valve valves are much less demanding than ball valves in terms of quality, and this is what has made them indispensable for a long time.
The type of taps that is popular today has a locking element made in the form of a ball. Despite the fact that this design has been known for more than a hundred years, they began to be used en masse not so long ago. This was due to imperfect technologies and difficulties in maintaining stable tightness of the connection of working elements.
The movable valve of a classic ball valve is a spherical plug, which has a hole made along the axis of the pipeline and across the axis of rotation of the locking element. The amount of working medium passing through the device is regulated by the angle of rotation from 0 to 900. Now, if you need to install shut-off valves, then in the vast majority of cases the decision is made to buy a ball valve. The ball type can also be selected as not only a closing device, but also a flow regulating device.

The material used is brass or bronze, as well as modern polymers. The ball valve, made of metal, has standard dimensions and is easy to install.
Gas valves are used in systems with a maximum pressure of 40 bar, at temperatures from -25 to +60°C. Tightness is ensured thanks to diamond processing and subsequent coating of rubbing parts with chromium or nickel, which eliminates rapid wear of the seals and allows the device to be used for many years.
There are a huge number of models for water - they are produced as a standard ball valve that can withstand up to 25 thousand cycles without maintenance or repair at operating temperatures from -20 to +150°C. For a more reliable connection, the reinforced product has an elongated thread.
