Abstract
In a method for assembling a needle valve having a housing, at least one valve needle longitudinally displaceably guided in the housing in a first spatial direction, and at least one valve seat plate, the plate for each needle has a valve seat associated with the needle, at which seat an outlet opening for a fluid can be closed and opened by back and forth movement of the relevant needle. In a first step the plate is fastened to the housing by a fastener such that it has limited movement with respect to the housing. In a second step each needle is set into a back and forth movement in which it is alternatingly placed onto and lifted up from the associated seat. In a third step the plate is fixed on the housing while the at least one needle moves back and forth.
