Proportional Directional Valve 4WRTE25W8-350L-4X/6EG24EK31/F1V - Bosch Rexroth R901363205

On the 4WRTE25W8-350L-4X/6EG24EK31/F1V the external X line is not needed because the pilot stage takes its oil internally. The return, in contrast, leaves the valve through Y and therefore stays separated from back pressure in the tank channel. The closed loop W8 spool meters 350 l/min nominal flow and up to 870 l/min for short periods.

Benefits

• Internal pilot supply saves the X line while the external return keeps the pilot stage relieved.
• 350 l/min nominal flow with a maximum flow rate of 870 l/min.
• Spool symbol W8 with three switching positions and internal closed loop control of the main spool.
• A 4 ... 20 mA current command value, 24 VDC supply and up to 350 bar operating pressure.
• FKM seals and a weight of 18.06 kg on connection diagram ISO 4401-08-08-0-05.

Application

Typical installations are presses and test rigs with a long, filtered return line. Mineral oil of class HL is intended. The valve mounts on a subplate to ISO 4401-08-08-0-05 with a 7-pole plug to EN 175201-804.
