FIELD: valving.
SUBSTANCE: control valve comprises actuating mechanism mounted in the chamber connected with the housing. The movable column is made for permitting movement along the axis by means of the actuating mechanism. At least a part of the movable column is hollow. The unit of the stop valve is mounted in part inside the movable column and made for permitting sliding parallel to the axis with respect to the movable column. The stop valve is mounted on the sleeve which is built in the gate of the valve. The valve is shaped so that the fluid flow from the inlet opening to the outlet opening causes the gate of the valve to move toward its open position.
EFFECT: enhanced reliability.
