Benefits
- Internal supply, external pilot return, independent of back pressure in the tank line.
- Command value 4 to 20 mA into on-board electronics, 24 V DC supply.
- 400 l/min nominal flow, up to 1550 l/min in size 32.
- Spool symbol W8, linear characteristic curve, with internal piston position feedback.
- 350 bar operating pressure, NBR seals, hydraulic fluid HL.
- 37.3 kg weight, connection diagram ISO 4401-10-09-0-05.
