The trend in thefieldofmedical devices, too, is towardsever smaller
and lighter equipment. At thesame time, theyhave tobemore cost-
effective thanpreviousmodelsandwithstand thestressof beingused
onadailybasis for longperiodsof time. Themarket demands faster
andmorepreciseanalytical devicesaswell asstate-of-the-artmedical
equipment. Festo isalreadyworking closelywith customers todevelop
customisedsolutions thatmeet thestringent requirements for gasand
PiezovalvesandminiaturevalvesMHare the ideal solution for small
flows inmedical technology. Their great technical featuresmake them
particularlywell suited tovalve functions in thefieldofmedical tech-
nologyaswell as formobileoxygensystemdevices, for example. They
worksilently, consumevery littleenergy, donot produceheat and can
operateproportionally. Small valves canbeused inawidevarietyof
applications, includingdialysismachines, surgical instruments, train-

Automationdoesnot necessarilymean
convertingall previouslymanual processes
tobecome fullyautomated. The transition
often takesplace insteps, fromautomat-

mentsof the laboratory. These remain
