Abstract (en)
The invention relates to a valve assembly (40) for a hydrocarbon wellbore (1). The valve assembly comprises an insert assembly (51,52,53) adapted for insertion in the production tubing or the Christmas tree. The insert assembly is provided with at least two passages (54,55); a lower (56,57) and upper (58,59) passage port for each said passage; a valve member (80) in at least one of said passages; and an operating mechanism (74) for operating the valve member. The passages each extend through the insert assembly from the accompanying lower passage port to the accompanying upper passage port. The lower passage port is arranged at the lower end of the insert assembly and the upper passage port is arranged at a distance above the lower end of the insert assembly. The valve member is operable between a flow position, allowing fluid flow between the lower passage port and upper passage port and a blocking position preventing fluid flow between the lower and upper passage port. The invention further relates to a Christmas tree (16) with such valve assembly, a retrofit assembly with such valve assembly, sub-surface use of such valve assembly, a hydrocarbon wellbore with such assembly and a method of retro-fitting a production flow valve with such valve assembly.
