Abstract: A fluid control valve for high pressure surges, that has a controlled pressure drop box inside, arranged on a block seat and through whose core a cylindrical plug can be moved. The box is formed by a number of disks grooved on both sides, fluid flows through the grooves. The grooves are arranged in a spiral, curved clockwise or counterclockwise and crossways to the grooves of the adjacent disks, forming a number of chambers at the intersections between the contact faces of two side-by-side disks. A dynamic mixture of the incoming fluid veins through each groove is produced in each of the chambers, with the ensuing creation of local turbulence and loss in kinetic energy as heat prior to evacuation through the protruding course of the outlet grooves. The successive chambers in the course of the grooves are arranged in tiered annular spaces of gradual and controlled pressure loss.

Abstract: Control valve for high pressure drop, which includes:(1) Seat ring with an extension on the lower side formed by a drilled cylinder(2) Cylinder which guides the plug and is also drilled in its lower side(3) Plug, with diameter decreasing in steps from the upper to the lower side, these plug diameters combined with the inside diameters of cylinder and seat ring, create inner chambers or intermediate stages, which divide the total pressure drop of the fluid across the valve in several smaller pressure drops, in a preferred design as shown in FIG. 1, there are 3 inner stages.(4) A lower ring chamber in between diameter of the plug (3) and the inner diameter of the seat ring (1).(5) A cylinder chamber, inside the plug (3) which is hollow, and(6) An upper ring chamber formed by the intermediate plug (3) diameter and the inner diameter of the cylinder (2).Chamber (4) and (6) are also balancing chambers in that the pressure around the plug is the same all around.
