FIELD: fittings, particularly shutoff and regulating means for pipelines used in power engineering and oil-refining machinery.

SUBSTANCE: device has outer case, stationary inner case arranged inside outer case and movable slide. Slide mate to inner case and may move to register windows formed in side surfaces of slide and inner case. Mating surfaces of slide and inner case are conical. Slide may rotate around inner case up to selected degree of window alignment by means of worm part connected thereto and worm member secured to outer case. Window shapes are selected from a given law of medium flow rate variation. Segmented cams with adjusting washer are disposed at slide end. Installed on inner case are ball runners.
