ABSTRACT:
A valve for controlling the flow of fluids, improved by utilizing a cartridge, containing a valve head and a valve seat, which is placed in a box-type valve body. The cartridge enables rapid exchange of the valve head and valve seat.
Thus, the improved valve is particularly suitable for use in pipe lines of nuclear power plants, in which radioactive substances flow.
