Flow control valve for fluidized material

A flow control valve for fluidized material comprising:

• a valve housing having a valve chamber with a valve seat;
• a valve plug having a flow passage, said valve plug being arranged inside said valve chamber in front of said valve seat so as to be rotatable about an axis of rotation for controlling a flow through said flow control valve and said valve plug comprises a cylindrical plug biasing surface;
• and
• at least one cantilever spring arranged in a clearance space opposite to said valve seat, said cantilever spring being fixed to said valve housing and having an end portion in contact with said cylindrical plug biasing surface so as to bias said valve plug against said valve seat perpendicularly to said axis of rotation for achieving a sealing contact between said valve seat and said valve plug.

• and
• an adjustment device supporting said second end portion of said cantilever spring, said adjustment device allowing the axial position of said cantilever spring with respect to said valve plug to be set.
