FIELD: machine building.
SUBSTANCE: facility for control of fluid medium flow consists of case with inlet, outlet and channel for forming trajectory of fluid medium; said channel runs from inlet to outlet. A ring of the valve seat is attached to the case; trajectory of fluid medium flow passes though this ring. Additionally, a cage with an internal channel is secured to the case; also the cage has at least one channel for trajectory of fluid medium flow. A control element matches the internal channel of the cage by size; the control element can travel along axis between opened and closed positions. The said element sets packing surface, directed, in essence parallel to axis. Packing can interact with packing surface when the control element is, in essence in closing position.
EFFECT: limited flow of fluid medium through aperture of ring of valve seat.
