This variant needs only the four main ports, since pilot oil is taken internally and returned internally. The 4WRZ32W8-520-7X delivers 520 l/min nominal flow with spool symbol W8 and weighs 43.74 kg. Operating pressure reaches 350 bar, and an integrated pressure reducing valve keeps the pilot stage steady.
