ABSTRACT:
The ball cock has a housing in which a valve ball is rotatably arranged. The sealing is effected by two sealing rings which are retained by cages. Disposed on each side of the ball cock is a spigot for welding the valve to the connecting pipes. The connection between the spigots and the flat parallel end surfaces of the housing and of the associated cage is produced by vibration welding. Absolutely no changes in dimension or shape occur and a strength is produced which corresponds to that of the plastic material. The ball cock is of simple construction and may be manufactured economically.
