Polyethylene ball cocks have been used in gas supply systems construction more often lately. The main advantage of such cocks in comparison with the traditional stop valves is that they do not need servicing during their operation life. Technical norms regulate the application of switching-off devices in gas supply systems. Switching-off devices for gas supply system, in particular, can be constructed under ground or above the surface with wells. The wells are not desirable on the main, as there are some definite regulations concerning their opening and work in them. This fact complicates greatly the usage of stop valves fixed on the active pipeline; as this unit needs constant attendance it causes problems for the organization.

If stop valves are set above the ground, in conformity with all gas supply technical regulations, the territory is to be fenced about; there are also some requirements to covering. Moreover, the territory for setting stop valves is not always available, as there can be its shortage. Using a ball cock you could avoid all these problems. Such cock is opened and closed with the help of a rod, going up to the surface, it can be dismountable as wells. The handle of the extension rod is installed under the "mat", and the cock itself is welded to the pipe with the help of thermo-resistant unions.

Any supporting piers or wells are not required in this case, the cock installed is in soil. If you compare the expanses for a ball cock with those of a gate valve, Если сравнить затраты на приобретение шарового крана и стальной задвижки, the last one will certainly be cheaper. However, mounting it you will have to take into account the setting of piers or wells, a subballast, cladding and the territory used. Mounting of a polyethylene cock facilitates greatly the process of stop valves erection, buying all required materials and the process of putting the object into operation.
