Abstract

Bei einem pneumatischen Stellungsregler (1) mit einem Arbeitsglied (3) und einer auf dieses wirkenden, zwei miteinander gekoppelte piezopneumatische Ventile (11, 12) umfassenden Ventileinheit (2) weist letztere einen Signaleingang (29) für ein elektrisches Steuersignal sowie einen an eine Druckgasversorgung anschließbaren Versorgungseingang (4), einen an das pneumatische Arbeitsglied (3) angeschlossenen Arbeitsausgang (5) und einen Entlüftungsausgang (6) für das Arbeitsmedium auf. Dabei weisen die Ventile (11, 12) jeweils ein Ventilgehäuse (31, 32) mit einem Aufnahmehohlraum (33, 34) und einen darin (31,32) dichtend einsetzbaren funktionsspezifischen Ventileinsatz (13, 14) mit einer durchströmten Schalteinheit (15, 16) auf. Der Ventilsitz (40, 41) und der mit diesem zusammenwirkende Ventilkörper (21, 22) sind an der Schalteinheit (15, 16) vorgesehen. In dem Ventilgehäuse (31,32) angeordnete Strömungskanäle (35, 36, 37) münden dergestalt in den zugeordneten Aufnahmehohlraum (33, 34), dass bei identischem Ventilgehäuse (31, 32) durch Austausch des Ventileinsatzes (13, 14) unterschiedliche Funktionscharakteristiken des betreffenden Ventils (11, 12) realisierbar sind.

In a pneumatic positioner (1) with a working member (3) and acting on this, two coupled piezopneumatische valves (11, 12) comprehensive valve unit (2), the latter has a signal input (29) for an electrical control signal and a to a compressed gas supply connectable supply input (4), one connected to the pneumatic working member (3) working output (5) and a vent outlet (6) for the working medium. In this case, the valves (11, 12) each have a valve housing (31, 32) with a receiving cavity (33, 34) and a function-specific valve insert (13, 14) which can be inserted sealingly therein (31, 32) with a flow-through switching unit (15, 16 ) on. The valve seat (40, 41) and the cooperating with this valve body (21, 22) are provided on the switching unit (15, 16). In the valve housing (31,32) arranged flow channels (35, 36, 37) open in such a way in the associated receiving cavity (33, 34) that with identical valve housing (31, 32) by replacing the valve core (13, 14) different functional characteristics of the relevant valve (11, 12) can be realized.
