FIELD: valving.
SUBSTANCE: stop-control valve comprises housing with inlet and output passages. The housing receives control gate valve connected with the rod actuated by the drive, stop gate valve connected with the rod, and additional gate valve at the end of the rod. The stop gate valve is mounted concentrically in the bottom section of the control gate valve to define ring passage connected with the inner space through the radial passages. The seat of the additional gate valve is made in the stop gate valve which is provided with the axial passage. The seat of the stop gate valve underlies the control seat.
EFFECT: enhanced reliability and reduced sizes.
