Summary: | The valve (1) has a valve drive (2) having a longitudinal axis (3) and separated from fluid. A valve position of the valve is more variable in a direction of the longitudinal axis. A valve membrane (30) is sealed against the valve drive by a valve chamber (4). The valve membrane and another valve membrane (20) are sealingly engaged in two valve positions on annular valve seats (5, 6) that are arranged in the valve chamber. The valve membranes are simultaneously moveable by transfer elements (80) and designed as plate membranes. The transfer elements are arranged outside of the valve chamber.
Die Erfindung betrifft ein Ventil (1) zur Steuerung eines Fluids, mit einem vom Fluid getrennten Ventilantrieb (2), wobei der Ventilantrieb (2) eine Längsachse (3) aufweist, in deren Richtung eine Ventilstellung des Ventils (1) veränderbar ist, wobei eine Ventilkammer (4) vorgesehen ist, die mittels einer ersten Ventilmembran (30, 30') gegen den Ventilantrieb (2) abgedichtet ist. Die Erfindung ist dadurch weitergebildet, dass die erste Ventilmembran (30, 30') in einer ersten Ventilstellung auf einem in der Ventilkammer (4) angeordneten ersten Ventilsitz (5) abdichtend anliegt. |
