An electromagnetically actuatable valve for hydraulic control devices in motor vehicles is embodied as a pressure-equalized seat valve in a mode of construction comprising a hydraulic part with a valve dome and an electrical part that can be slipped onto the valve dome. In a magnet valve that is normally open, the tubular tappet that supports the closing member is supported at one point in a first bearing point, in terms of the longitudinal direction, that is embodied as a slide bearing, and a bearing ring that forms the sealing point accomplishes the hydraulic pressure equilibrium with the effective sealing diameter of the closing member that together with the valve seat forms the second bearing point. With the valve, very short switching times, in particular less than 0.5 ms, can be achieved with an economical mode of construction.

Electromagnetically actuatable valve

The invention relates to a check valve with a tubular valve housing in which a valve ball is received. To make a large flow cross section available and to prevent closure by the valve ball when the check valve is fully open, a perforated disk is press-fitted between longitudinally extending guide ribs of the valve housing and a circumferential wall of the valve housing there is an interstice as an outflow opening, which is not closed even the valve ball contacts the perforated disk. The valve housing is made by stamping, in which the guide ribs and a valve seat are made in one operation and are thereby aligned exactly with one another. In this way, a small radial play of the valve ball can be realized.
