FIELD: mining.
SUBSTANCE: controlled well electromechanical valve consists of a body, a connecting wet contact, a drive including a micro electric motor fed from the zero point of the centrifugal pump motor, and a reducer with an output shaft rigidly connected to the screw nut, inside of which is a screw coaxially articulated with a hollow stem with a hole for measuring the pressure in the formation. A movable differential piston, levelling well and reservoir pressure, is mounted on the hollow stem. At the free end, the hollow shaft is hermetically articulated with an auxiliary hollow valve and a saddle with an outlet channel into the wellbore, placed in the inner cavity of the controllable hollow valve with a seat regulating fluid flow from the formation.
EFFECT: increasing the reliability of the valve.
