摘要：The invention relates to a spray dampening system in printing presses, comprising: a rotating roller ( 2 ); nozzles ( 3 ) facing the roller; a pressurized piping ( 11 ) for supplying water or other fluid to the nozzles; control valves ( 7 ), along with electrical actuators therefor, in association with each nozzle, said control valves including a closing and opening spindle ( 1 ). Said electrical actuators comprise: an adjustment rod ( 5 ) of some MSM material, having its first end in contact with the spindle ( 1 ) and its second end resting against a stationary base ( 10 ), a return element ( 12 ), as well as a coil assembly surrounding the adjustment rod for establishing a magnetic field ( 14 ) applied to the adjustment rod. The field intensity enables changing the adjustment rod length and setting a spindle position in the control valve for thus regulating the amount of water or fluid flowing through the nozzles ( 3 ) as a spray ( 8 ).
