FIELD: valve industry.

SUBSTANCE: invention relates to shutoff and control valves, in particular to ball valves with throttling elements, and is intended for use in hydraulic systems, pneumatics, in various industries, power engineering, military devices, medicine. Ball valve comprises composite body with inlet and outlet branch pipes, ball rotary gate with through hole, rod, rod seal, seats of ball rotary gate. In the through hole of the ball rotary gate a throttling element is attached, which is a plate with holes attached to the inner wall of the through hole of the ball rotary gate, free edge of the plate is curved and has triangular cuts, the depth of which increases from the centre of the plate to its edges, and holes on the plate are staggered.
