FIELD: interruption and distribution of flow of liquid in hydraulic lines. SUBSTANCE: rod is connected with shut-off member in form of plate. Ratio of plate height to its diameter is less than one. Lateral and upper parts of plate are made in form of body of revolution whose thickness reduces to periphery and curvilinear generatrix. Sealing surface of seat is located below hole of inlet branch pipe by amount lesser than half the plate height. Cover has concave inner surface whose bottom is located above edge of hole of inlet branch pipe by amount lesser than half the plate height. In extreme upper position plate is located in spaced relation to inner surface of cover. Shape of inner surface of cover is identical to that of upper surface of plate. EFFECT: enhanced reliability. 2 cl, 1 dwg
