Abstract
An obturation valve is described for controlling a flow of molten material exiting from a nozzle into a mold cavity, comprising a channel for the molten material extending along a first axis, two or more obturating members that are mounted movably along a respective second axis inclined at an acute angle with respect to the first axis and so that a free end of each obturating member can move and converge towards the same point inside the channel. The free ends of the obturating members can join at said point to compose a blocking/closing bulkhead for the molten material.
