Abstract: A system for treatment of a biomass material, said system comprising: a first vessel (3) in which said biomass material is treated under a first pressure; a second vessel (5) in which said biomass material is received and held at a second pressure which is lower than the first pressure; a transporting pipe (7) connecting an outlet (9) of the first vessel (3) with an inlet (11) of the second vessel (5) for transporting the biomass material from the first vessel to the second vessel; and a valve (15; 15′; 15) arranged in said transporting pipe (7), said valve being configured for controlling the flow of biomass material and fluid in the transporting pipe (7), wherein said transporting pipe (7) is asymmetrically connected to an outlet (33′; 33) of said valve (15; 15′; 15) such that a generated jet stream of biomass material delivered out from the outlet (33′; 33) of the valve (15; 15′; 15) is received closer to a transporting pipe longitudinal central axis (A1) than if the outlet (33′; 33) of the valve (15; 15′; 15) and the transporting pipe (7) would have been connected symmetrically.
