Die Ventilkammer (2) im Ventilgehäuse (1) ist mit einem Arbeitsanschluß (A) über einen ersten Ventilsitz (3') mit einem Druckanschluß (P) und über einen zweiten Ventilsitz (14) mit einem seitlich am Ventiloberteil (6) angeordneten Rücklaufanschluß (R) verbunden. Zwischen den Ventilsitzen (3', 14) ist der beidseitig wirkende Ventilteller (12) angeordnet, der über einen durch den zweiten Ventilsitz (14) geführten Ventilschaft (11) mit einem Magnetanker (8) verbunden ist, der dichtend und reibungsarm in einem Führungsrohr (10) geführt ist um das die Magnetspule (7) angeordnet ist. Die wirksame Querschnittsfläche des Magnetankers (8) ist größer oder kleiner als der wirksame Querschnitt der Ventilsitze (3', 14) und der Raum zwischen dem Magnetanker (8) und einem Kopfstück (9) des Magnetsystems ist über einen durch den Magnetanker (8) und dem Ventilschaft (11) geführten Verbindungskanal (22) mit dem Raum unterhalb oder oberhalb des Ventiltellers (12) verbunden Das vor allem als Pulsatorventil verwendbare Ventil benötigt nur sehr geringe Betätigungsleistung und zeigt sehr geringen Verschleiß bei hoher Schalthäufigkeit.
