The closure element is designed to block and release a flow path and has a first axial end arranged remotely from the flow path and is connected to the pin, and a second axial end arranged in the flow path, and a housing which receives at least the pin and the first axial end of the closure element. At least in a region of its first axial end, the closure element has a radially circumferential seal with an outwardly protruding seal lip. The seal lip lies sealingly against a region of the housing in a closed state of the valve, and the seal lip has at least one radially circumferential bead.

The solenoid includes a coil, an armature, an upper stator, and a lower stator, and the stators are designed such that, when a magnetic force acts between the stators, the armature moves axially, further comprising a pin firmly connected to the armature, a cup-shaped piston connected to the pin, a spring, which moves the piston away from the solenoid in the event of a loss of the magnetic force, and a socket arranged on the housing to supply the solenoid with electric energy. A protective sleeve separates the region of the piston from the region of the socket in such a way that no medium from the region of the piston can reach the region of the socket, is arranged in the solenoid.
