Description

Where a dedicated control oil supply exists, the main valve should make use of it. The 4WRKE16W8-220L-3X/6EG24K31/F1D3V is designed for external pilot oil supply and external return and carries 220 l/min nominal flow at up to 350 bar.

Advantages

External pilot oil supply and external pilot oil return
220 l/min nominal flow, maximum flow 460 l/min
Spool symbol W8, linear characteristic curve, three switching positions
Command value 4...20 mA, on-board electronics with internal spool position feedback
Maximum operating pressure 350 bar, FKM seals for HL
24 VDC, interface ISO 4401-07-07-0-05, 10.98 kg

Applications

Valves of this kind sit in large hydraulic systems where a small pump feeds the control circuit. The separate supply keeps switching times independent of load pressure. A connector 7-pole (6 + PE) according to EN 175201-804 is enough for wiring.
