The 4WRLD16E250LJ-4X/MXT/24ND6T draws pilot oil from an external circuit yet returns it internally into the tank channel. Pilot pressure therefore stays independent of working pressure while one line in the manifold disappears. The spool of symbol E releases 250 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply for constant pilot pressure, internal drain saves one line.
- 250 l/min nominal flow, up to 800 l/min maximum flow, operating pressure to 350 bar.
- Spool symbol E, 3 switching positions on 4 ports, size 16 body.
- Integrated digital axis controller, +/-10 V command value, 24 VDC supply.
- 12-pole connector (11 + PE) to EN 175201-804, mounting pattern ISO 4401-07-07-0-05.
- NBR seals for hydraulic fluid HL, mass 12.6 kg, UKCA to EMC SI2016/1091.

Applications
This piping is right where a pilot pressure circuit exists while the return line carries little back pressure. Test rigs plus forming machines with central pilot supply are typical. The control loop closes on the valve, an amplifier card in the cabinet is unnecessary.
