Setting the pressure reduction valve (Feeder)
The different functions of the tiltrotators require different quantities of oil. The
pressure reduction valve controls the oil quantity required for the individual
functions. The feeder values of the pressure reduction valve for the individual
functions must be carefully selected as they have a major influence on the
behaviour and the performance of the tiltrotators.
