A B S T R A C T The pressurization and depressurization of a container, and specifically a feed hopper for materials to be delivered to the interior of a blast furnace, is accomplished with the aid of pressure equalization devices which each include a valve and a wear and sound reducing mechanism immediately down- stream of the valve. The wear and sound reduction mechanism subdivides the stream of gas, which may contain entrained particulate matter, into a plurality of jets which are caused to follow a zig-zag trajectory.
