Abstract

Ein Ventil (1), insbesondere ein fremdkraftbetätigtes Wege-Sitzventil, mit einem in einem Ventilraum (3) eines Ventilgehäuses (5) verfahrbar angeordneten Ventilelement (7) zum Führen von unter einem Mediendruck stehenden Fluidströmen und zum wahlweisen Freigeben oder Sperren einer Verbindung (9) zwischen einem Versorgungsanschluss (11) und mindestens einem Nutzanschluss (13), das auf vor- und rückseitig gelegenen Querschnittsflächen (15, 17) mit dem jeweiligen Versorgungsdruck (p) beaufschlagbar ist, ist dadurch gekennzeichnet, dass für ein unabhängig von dem jeweils herrschenden Mediendruck führbares Ventilelement (7) der in den Ventilraum (3) ragende Bereich (19) des Ventilelements (7) eine weitere Querschnittsfläche (21) aufweist, welche flächenmäßig einer, dem Ventilraum (3) abgewandten, weiteren wirksamen Querschnittsfläche (23) entspricht und dass diese beiden weiteren Querschnittsflächen (21, 23) einem regelmäßig vom Medien- und/oder Versorgungsdruck (p) unterschiedlichen Druck (po) insbesondere gebildet durch den Umgebungsdruck, gleichermaßen ausgesetzt sind.

A valve (1), in particular a power-operated directional control valve, with a valve element (7) movably arranged in a valve chamber (3) of a valve housing (5) for guiding fluid flows under a medium pressure and for selectively releasing or blocking a connection (9 ) between a supply connection (11) and at least one utility connection (13), which can be acted on on the front and rear cross-sectional surfaces (15, 17) with the respective supply pressure (p) is characterized in that for a regardless of the prevailing Mediendruck feasible valve element (7) in the valve space (3) projecting portion (19) of the valve element (7) has a further cross-sectional area (21) which in terms of area, the valve space (3) facing away, further effective cross-sectional area (23) and that these two further cross-sectional areas (21, 23) a regularly from the media and / or supply pressure (p) untersc any pressure (po) formed in particular by the ambient pressure, are equally exposed.
