FIELD: controlling devices.
SUBSTANCE: group of inventions relates to a device and methods for automated control of a fitting. The device for automatic control of a fitting valve contains a controller. The controller is made with the possibility of controlling a position of the fitting of the fitting valve by means of the first control circuit in response to the choice of the first of a set of detectable operating modes. The controller is also made with the possibility of controlling the wellhead pressure by means of the second control circuit in response to the choice of the second of the set of detectable operating modes. The wellhead is functionally connected to the fitting valve. A method for automatic control of the fitting valve and a machine-readable carrier are claimed.
EFFECT: reduction in the degree of human intervention necessary to maintain the wellhead pressure and the position of the valve fitting within required values.
