Proportional Directional Valve 4WRTE25W8-350L-4X/6EG24K31/A1V - Bosch Rexroth R901094207

Many axis controllers output their command value as a voltage. The 4WRTE25W8-350L-4X/6EG24K31/A1V accepts that value directly as ±10 V and converts it into a spool position through the on-board electronics. At 350 l/min nominal flow and up to 870 l/min the pilot stage is fed and relieved through its own X and Y lines.

Benefits

• Analogue ±10 V voltage command value, usable directly with controllers that have an analogue output.
• 350 l/min nominal flow with a maximum flow rate of 870 l/min.
• External pilot oil supply and external return for a separated pilot stage.
• Closed loop W8 spool with three switching positions up to 350 bar.
• FKM seals, a valve weight of 18 kg and connection diagram ISO 4401-08-08-0-05.

Application

The valve is used on large control axes in presses, rolling mills and test plants with their own pilot circuit. Mineral oil of class HL is intended. The electrical connection is a 7-pole plug to EN 175201-804.
