VALVE DEVICE AND FILLING METHOD

摘要

The invention relates to a valve device, comprising a first and a second controllable tube pinch valve (38a, b) each having a firm tube seat (40a, b) and each having a squeezing plunger (50a,b) which is movable relative to the firm tube seat (40a, b) and is biased by spring force in the direction of said tube seat, wherein the squeezing plunger can be moved by means of a force generating unit (56a, b) in the activated state of said unit against the spring force into a predetermined open position. The invention is characterised in that in the second tube pinch valve (38b) the travel of the squeezing plunger (50b) in the direction of the bias is limited by an adjustable stop (70b).
