perforation column valve configured to be affixed to a casing to connect the perforation to a probe, method for preparing a perforation column valve to be connected to a casing to connect a perforation to a probe, perforation column valve configured to be affixed to a jacket to connect a drill to a probe and method to control a drill column valve. It is a method and a drill column valve (70, 160) for closing a conduit through which a high pressure fluid flows. the drill string valve (70, 160) includes an elongated housing (162) having an inner cavity (79), a sealing member (56) affixed to a first end (74) of the elongated housing (162). that the sealing member (56) is disposed within the inner cavity (79) so that a flow of liquid (80) through the inner cavity (79) from the first end (74) to a second end (76) is allowed. a sliding valve (50) configured to slide to and from the sealing member (56) so that when the sliding valve (50) contacts the sealing member (56) the flow of liquid is suppressed; propensity cartridge (90) configured to apply a first force on the sliding valve (50), and a loading mechanism (110) configured to apply a second force on the propensity cartridge (90).
