Abstract: Controllable solenoid valve in which, due to the interaction between a magnetic force caused by an electrical flow and a spring force acting against the magnetic force, at least one first sealing body in the interior of a valve housing is displaced in axial direction between two final positions whereby moving relative to its first sealing seat. The interior extends from one electromagnet to a connection. To enable, in a simple manner, a specific reproducible influencing of the sequence speed of cylinder controls in hydraulic drives and to prevent uncontrolled movements by these drives, the first sealing seat up to the first sealing body is provided with an axially extending cylindrical housing inside of which a slide is axially displaced according to the electrical flow.
