When the tank line carries return oil from several consumers, pressure there fluctuates. The 4WRKE25W8-220L-3X/6EG24EK31/A1D3V therefore drains pilot oil externally and runs 220 l/min nominal flow at 350 bar.

Description

A fluctuating tank pressure acts back on the pilot stage when pilot oil drains through the same channel. The 4WRKE25W8-220L-3X/6EG24EK31/A1D3V draws pilot oil internally and drains it externally, with spool symbol W8 and FKM seals.

Benefits

Internal pilot oil supply, external pilot oil return, pilot stage free of tank back pressure
FKM seals for elevated oil temperatures
Spool symbol W8, nominal flow 220 l/min, maximum flow 870 l/min
Command value ±10 V, on-board electronics, 24 VDC supply
Maximum operating pressure 350 bar, size 25, weight 17.85 kg
Linear characteristic curve, ISO 4401-08-08-0-05 interface

Application

Intended for systems with a return filter or cooler in the tank line where pressure builds up. The separate return keeps the behaviour of the pilot stage even. Subplate mounting follows ISO 4401-08-08-0-05 and takes hydraulic fluid HL.
