Abstract: A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation.
