A valve arrangement configured to dispense a fluid, the valve arrangement having a valve plate for fixing the valve arrangement to a container, a valve housing and a fixing part for fixing the valve housing to the valve plate,
- the valve plate having a receiving space, the valve housing being received in the receiving space,
- the fixing part having a first portion and a second portion projecting radially from the first portion,
- the first portion being cylindrical or conical and being received in the receiving space of the valve plate,
- the second portion being flange-like or collar-like and being laser-welded or ultrasonically welded with an underside of the valve plate, and
