Proportional Directional Valve 4WRTE25W8-350L-4X/6EG24EK31/A1V - Bosch Rexroth R901090630

The 4WRTE25W8-350L-4X/6EG24EK31/A1V combines straightforward analogue control at ±10 V with a piping arrangement that needs only one external line: pilot oil is taken internally and the return goes to tank through Y. The closed loop W8 spool delivers 350 l/min nominal flow, up to 870 l/min at maximum.

Benefits

• Analogue ±10 V command value through the on-board electronics, with no separate amplifier required.
• Internal pilot oil supply with an external return, so only one additional line on the manifold.
• 350 l/min nominal flow with a maximum flow rate of 870 l/min.
• Closed loop W8 spool with a linear characteristic curve and up to 350 bar operating pressure.
• FKM seals and a valve weight of 18 kg on mounting pattern ISO 4401-08-08-0-05.

Application

The version suits large feed and lifting axes with a long return line. Mineral oil of class HL is the operating fluid, and the FKM seals widen fluid compatibility. Connection is via a subplate to ISO 4401-08-08-0-05.
