ABSTRACT:
The valve includes one or two perforated seals having flat surfaces that can move in translation or rotation in their plane, placed between two fixed parts provided with passages for the fluid, which flows in direction perpendicular to the plane of the seals. The seals are composed of two disks turning in opposite ways around a common shaft and including multiple perforations. The passages in the two fixed elements are composed of multiple channels each having a relatively small section. The flow is regulated by moving the seals to change the number of channels which are opened or closed. The value can be used for adjustment or regulation of fluid flow and/or pressure.
