The present invention provides a two-stage electromagnetic valve (50) for use in controlling fluid flow between first and second passageways (P1;P2) in a hydraulic valve block (2), comprising: a one-piece valve body (200) defining a central axis (B) and having a central opening (201) therethrough, the central opening (201) having a first diameter, the valve body (200) having a lower end (204) adapted to be inserted into a bore (19) of the valve block (2) and provided with a lower cylindrical opening (207), the lower end (204) of the valve body (200) including a radially inwardly extending shoulder (218) defining a valve seat (218) and a cylindrical tubular portion (216) extending downwardly from the valve seat (218), the cylindrical tubular portion (216) having a second diameter smaller than the first diameter; an armature (206) axially moveable within the valve body (200) and spring (224) biased in one axial direction (57A); a closing element (30) carried by a lower end (210) of the armature (206); an electromagnetic coil (64') coaxially surrounding the armature (206) and operable to effect axial movement of the armature (206) in an axial direction (57B) opposite the one direction (57A); a cage (246) having a central opening (251) therethrough, the cage (246) having an upper end (248) attached to the lower end (210) of the armature (206) and a lower end (250); and a poppet (226) having a bore (238) therethrough, the poppet (226) disposed within the central opening (251) of the cage (246) and spring (244) biased away from the lower end (210) of the armature (206); the lower end (250) of the cage (246) having a radially inwardly extending cage shoulder (252) defining a cage opening (254); a lower end of the poppet (226) is engageable with the valve seat (218); and a seal (262) carried by the lower end (204) of the valve body (200), the seal (262) engageable with the bore (19) of the valve block (2).
