A valve block for use in the control of a multi-adsorber pressure-change adsorption installation serving for the adsorptive separation of gas mixtures has pressure-operated, preferably diaphragm-type, adsorber valves (2) therein. The adsorber valves allocated to an adsorber are connected in a row with one another through an adsorber gas conduit (1). The valve block has recesses (3) on the adsorber valves, forming parts of the adsorber gas conduits. Pipes (6) form annular gaps with the recesses 3 and each pipe leads by way of cross-type junction (5) to product gas conduits (4). The axis of each pipe (6) leading to the product gas conduit and the axis of an adsorber gas conduit intersect. Each product gas conduit (4) thus leads by way of the cross-type junction (5) to several adsorber valves arranged in different adsorber gas conduits (1) and thus is in communication with all adsorbers. <IMAGE> |
