Abstract
A well tool device includes a housing with a through bore having a first end and a second end. A frangible obstruction device is provided inside the longitudinal bore, where fluid flow between the first end and the second end is prevented due to the frangible obstruction device. The frangible obstruction device includes a through opening. The well tool device further includes an actuation device extending fluid-tight at least into the through opening. The actuation device includes an actuation tool connection interface and a disintegration device. The disintegration device is configured to be at least partially moved into the frangible obstruction device and thereby provide disintegration of the frangible obstruction device, hence allowing fluid flow between the first end and the second end of the through bore.
