Abstract
A valve for adjusting a fluid flow includes a valve cartridge with at least one first fluid opening, at least one second fluid opening, a preliminary stage with a first valve seat and a first closing element, and a main stage with a second valve seat and a second closing element. The first valve seat is at a first axial through-opening of the second closing element, which is at least partly in a preliminary stage sleeve. The first valve seat is within the preliminary stage sleeve, and a flow path from the at least one first fluid opening to the preliminary stage leads through at least one inflow opening, which is radially introduced in the preliminary stage sleeve. An axial filter gap formed between an actuation element and the preliminary stage sleeve overlaps the at least one inflow opening at least in some regions and together form a filter.
