Hydraulic drives in water engineering stand still for long periods and should start without a jolt when called upon. The 4WRZE10E1-50-7X/6EG24N9K31/A1V meters 50 l/min rated flow at 315 bar maximum and is fed from a separate pilot circuit that stays filtered independently of the main line.
Benefits
- External pilot oil supply and external pilot oil return, a separate filtered pilot circuit is possible.
- 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
- Spool symbol E1, three switching positions, size 10 to ISO 4401-05-05-0-05.
- Concealed manual override for emergency service without control voltage.
- Command value 10 V bipolar, 24 VDC supply, 8.06 kg, FKM seals for HL fluid.
