Abstract
A safety valve for wells for the extraction of hydrocarbons is described which allows the cutting of the tubular drilling material possibly present in the safety valve and the closure of the well with a hydraulic seal, allowing the subsequent application of appropriate intervention plans to control the well in case the BOPs are not effective. A safety valve for wells for the extraction of hydrocarbons is described which is able to perform the action of cutting the tubular material with a higher capacity than conventional BOPs, considering the worst conditions of compound stresses at the wellhead, which are not contemplated by such BOPs today. In particular, the safety valve is capable of cutting/shearing a wide range of tubular elements in its inside.
