ABSTRACT:
A valve (1) has a valve housing (2) traversed by a through-flow channel (3), a valve seat (5) in the through-flow channel (3), and a closure member (13) movable relative to the valve seat (5), wherein the membrane (28) is attached on the outside to the valve housing (2) and on the inside to the closure member (13), whereby a seal (24) is provided on the side of the membrane (28) facing away from the through-flow channel (3) between closure member (13) and valve housing (2), which encloses a support hollow space (29) together with the membrane (28) filled with a non-compressible deformable support medium, wherein the closure member (13) has a shape such that, on the side of the membrane (28) facing away from the through-flow channel (3), the volume of the support hollow space (29) remains essentially constant during movement of the closure member (13).
