FIELD: valve industry.

SUBSTANCE: invention refers to valve industry. Axial-type control valve comprises an outer and an inner housing, inlet and outlet branch pipes with flanges, a flow divider, a shutoff element with a translation drive. Vertical rack is arranged with a gap in vertical support sleeve, which is installed in internal housing, is located in vertical plane of symmetry of valve and is shifted towards inlet branch pipe relative to middle of distance between flanges, horizontal rod is installed in cylindrical guide, which on outer surface, in central part, has flange. End of horizontal rod, located on the side of inlet branch pipe, is installed with a gap in guide bushing, which is fixed to end of inner housing on the side of inlet branch pipe. Axes of vertical rack and horizontal rod intersect in central part of cylindrical guide. At that, profiles of teeth of vertical rack and horizontal stock have rectangular shape, and depth of cavities between teeth is equal to half of diameter of horizontal rod.

EFFECT: valve has high throughput capacity in open position, can operate in different conditions and temperature modes without wedging of horizontal rod and vertical rack, and also provides convenience and simplicity during assembly-disassembly.
