An electromagnetically actuated valve of a hydraulic unit is received in pressure-tight fashion and mounted without complicated adjustment of the valve stroke. The valve comprises a hydraulic part and an electrical part. The hydraulic part is a pre-mounted unit with a stroke of a seat valve set before insertion into a receiving bore of a metal valve block. The hydraulic part is received in pressure-tight fashion in the valve block by a first swaged connection located between an inlet conduit and an outlet conduit of the receiving bore. A sealing ring that closes off the receiving bore is retained by a radially extending flange of a bushing slipped onto the hydraulic part. The flange is secured to the valve block by a second swaged connection. The hydraulic unit is usable for traction-controlled motor vehicle brake systems.
