Description

When system pressure swings with the machine cycle, the pilot stage should not notice. On the 4WRZ25W8-325-7X/6EG24N9K4/V both pilot feed and pilot drain run externally, while the main stage meters 325 l/min nominal flow at up to 350 bar.

Benefits

External pilot oil supply plus external pilot oil return, pilot pressure untouched by working pressure
Nominal flow 325 l/min, maximum flow 870 l/min
Spool symbol W8, 4 ports, 3 switching positions
Maximum operating pressure 350 bar in size 25
External electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804
FKM seals, concealed auxiliary actuation, weight 20.02 kg

Application

The valve is meant for presses, roll adjustment drives as well as test rigs with strongly changing load pressure. External pilot routing keeps response time constant across the whole cycle. Connection diagram ISO 4401-08-08-0-05, weight 20.02 kg.
