Proportional Directional Valve 4WREE10E1-25-3X/V/24A1 - Bosch Rexroth R901582126

With a ±10 V command the sign sets the direction of travel and the magnitude sets the speed, so no second enable signal is required. In this variant the 4WREE10E1-25 carries 25 l/min nominal flow, opens to as much as 180 l/min maximum flow at peaks and holds 350 bar. Spool symbol E1 blocks all four ports in mid position.

Benefits

• ±10 V command value, direction from the sign, speed from the magnitude
• 25 l/min nominal flow, up to 180 l/min maximum flow
• Spool symbol E1 with a closed centre, three switching positions, four ports
• Operating pressure up to 350 bar, subplate mounting to ISO 4401-05-04-0-05
• On-board digital electronics, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804
• 7.3 kg unit weight, FKM seals, HL hydraulic fluid, UKCA conformity for EMC SI2016/1091

Application

The valve matches controllers with a ±10 V analogue output module, common in machine tools, test equipment and special purpose machinery. Direct actuation without a pilot stage keeps the assembly simple. For plants with long signal runs the sister version with 4...20 mA is preferable.
