Abstract
The system can be applied to that type of valve in whose base body 1 there is a box 2 acting as guide means for a closing-off device 5 capable of closing orifices 8 located in the wall of the box 2. Said closing-off device 5 has an extension or frustoconical tip 11 which, depending on the opening or displacement thereof, has a series of grooves 10 made in the inner inclined surface of a ring/seat 16 mounted on the body 1 of the valve, as axial continuation of the box 2, producing expansions/restrictions of the volume which directly affect the fluid in order to produce pressure jumps which are intermediate between the inlet pressure 9 and the outlet pressure 4, thereby preventing cavitations and therefore the wear of the internal parts of the valve.
