Abstract
A valve for controlling fluids, in particular hydraulic fluid, includes a first connector opening and a second connector opening, a preliminary stage with a first valve seat and a first displaceable closing body, and a main stage with a second valve seat and a second displaceable closing body. The first valve seat is assigned to a through opening of the second closing body. A filtering gap is formed in a flow path from the first connector opening to the preliminary stage by way of a constriction of the flow path.
