AbstractAbstract
[en] A closing valve is described designed for use in large diameter pipes for the transport of dangerous and harmful media in nuclear power facilities. The valve assembly consists of a leak-proof cover, a double-side spindle closure and two parallel seats placed in the through-flow axis of the valve body. The design of the valve spindle closure allows closing pipe mains of large diameter at high operating pressures without the danger of disturbing the tightness of the valve. (J.B.)

AbstractAbstract
[en] A rapid-action large-diameter valve and control fitting was designed for cooling circuits of nuclear power plants with fast liquid metal cooled reactors, namely sodium cooled. The design meets the requirements for axial symmetry about the flow axis and secures the equilibrium of hydraulic and hydrodynamic forces observing the uniformity of the thickness of the fitting walls which is a pre-requisite for good resistance to thermal shock. (F.M.)
