Frequently Bought Together

Spool symbol W8 defines how the 4 ports are linked in the 3 switching positions. The 4WRLE25W8-350LJ-4X/MXY/24A1 proportional directional valve carries that symbol at size 25 and meters 350 l/min nominal flow at up to 350 bar operating pressure.

Benefits

  • 350 l/min nominal flow - flow up to 1250 l/min, installed weight 18.95 kg.
  • Spool symbol W8 - 3 switching positions across 4 ports, internal spool position feedback for a linear characteristic.
  • Pilot oil external through X and Y - pilot control stays independent of working and tank pressure.
  • ±10 V command value on the on-board electronics - 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
  • Maximum operating pressure 350 bar - subplate mounting ISO 4401-08-08-0-05, NBR seals for HL hydraulic fluid, CE conformity.

Applications

The valve is intended for main axes on test rigs, presses and special purpose machines with their own pilot oil supply. A separate pilot circuit keeps actuating time constant even when working pressure varies over the cycle. The ±10 V voltage command connects to existing analog cards without a signal converter.

Manufacturer
