System for applying of fluids on rollers in an offset rotary printing press comprising at least a plate cylinder, an offset cylinder and a print cylinder and dampening rollers bearing against the plate cylinder, which dampening rollers are dampened from a number of nozzles provided on a bar (1A-1N) in parallel to the rotation axes of said rollers and from which nozzles is emitted dampening medium in atomized form whereby every nozzle (2) in said bar (1) forms a common outlet for a first medium in the form of dampening water, and a second medium in the form of wash fluid, whereby the supply of dampening water (51) and wash fluid (61) to said nozzle is opened and closed by means of an electrically controllable combination valve (11; 11'), the two valves (13, 14; 13', 14') of which for the supply pipes (51, 61) are controlled individually according to different operation programs from a central electronic control unit (100). |
