An electromagnetic valve for use in controlling fluid flow between first and second passageways (P1, P2) in a hydraulic valve block, comprising: a valve body defining a central axis and having a central opening therethrough, the valve body having a lower end adapted to be inserted into a bore of the valve block, a radially extending notch being formed in the lower end of the valve body, and an axially extending groove being formed from the radially extending notch in an outer surface of the lower end; a hollow valve dome attached to an upper end of the valve body; an armature axially moveable within the valve dome; a spring for biasing the armature in one axial direction; a closing element coupled to a lower end of the armature; an electromagnetic coil coaxially surrounding the armature and operable to effect axial movement of the armature in an axial direction opposite the one axial direction; a valve seat member carried by the lower end of the valve body and having an orifice providing fluid flow between the first and second valve block passageways (P1, P2), the valve seat member defining a valve seat surrounding the orifice and cooperating with the closing element for selectively closing the orifice, a filter assembly mounted on the lower end of the valve body, the filter assembly having a fluid outlet opening formed in an outer wall thereof; wherein the valve seat member is formed as a deep drawn part and includes a tubular inner wall defining an inner tubular portion concentrically arranged within a tubular outer wall defining an outer tubular portion, the inner tubular portion and the outer tubular portion connected by a radially extending wall, an inside surface of the outer tubular portion engaging an outside surface of the lower end of the valve body, wherein the radially extending notch and the axially extending groove define a fluid flow path between the valve body and the valve seat member, and wherein the inner tubular portion is formed to include a circular edge facing upwardly in the direction of the armature, and including a reduced diameter section spaced downwardly from the circular edge to define the upwardly facing valve seat and the valve orifice; an annular fluid flow path is defined between an outer surface of the inner tubular portion and a surface of the central opening of the valve body, the annular fluid flow path extending axially and circumferentially about the inner tubular portion from the upwardly facing valve seat to the radially extending wall; and a radially extending fluid flow path is defined between the annular fluid flow path and the first passageway formed in the valve block, and extends through the radially extending notch, the axially extending groove and the fluid outlet opening of the filter assembly. a valve body defining a central axis and having a central opening therethrough, the valve body having a lower end adapted to be inserted into a bore of the valve block, a radially extending notch being formed in the lower end of the valve body, and an axially extending groove being formed from the radially extending notch in an outer surface of the lower end;
