Abstract
A flow control valve for fluidized material comprises a valve housing having a valve chamber with a valve seat and a valve plug having a flow passage, the valve plug being arranged inside the valve chamber in front of the valve seat () so as to be rotatable about an axis of rotation for controlling a flow through the flow control valve. It further comprises spring means biasing the valve plug against the valve seat perpendicularly to the axis of rotation, for achieving a sealing contact between the valve seat and the valve plug. According to an important aspect of the invention, the spring means comprises at least one cantilever spring () arranged in a clearance space opposite to the valve seat () so as to bias the valve plug against the valve seat.
