On a deck crane the load pulls on the rope one moment and pushes back the next. The 4WRZE10W8-50-7X/6EG24N9TK31/F1V keeps flow at its 50 l/min rated value through that change, at 315 bar maximum, with a blocked centre that holds the hook.
Benefits
- Spool symbol W8 blocks at centre and holds the load without actuation.
- 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
- External pilot oil supply with internal pilot oil return, without a pressure reducing valve.
- Current command value 4...20 mA, insensitive to long cable runs on board.
- Concealed manual override, 7.98 kg, size 10, FKM seals for HL fluid.
