ABSTRACT:
A valve for controlling the flow of dangerous fluids includes a housing having a housing member equipped with connecting nipples and with a valve seat formed on a discrete seat member, a magnet-supporting socket connected to the housing member and bounding a compartment therewith, and a valve member accommodated in the compartment and displaceable toward and away from the seat to control the flow of the fluid through the compartment between the connecting nipples. A layer of corrosion-resistant material is explosion welded to and covers the internal surface of the housing. The magnet-supporting socket includes two components of materials which are incapable of being welded to one another in a melt-welding operation, the components being connected to one another by explosion-welding. The housing member is deformed from an originally cylindrical to a spherical configuration during the explosion-welding operation which welds the layer of the corrosion-resistant material to the internal surface of the housing member. The seat member is explosion-welded to the housing member and may be a composite of two layers one of which is of a corrosion-resistant material and faces the compartment, and the other of which is of the material of the housing member and is juxtaposed with and explosion-welded to the housing member.
