Proportional Directional Valve 4WREE10E1-50-3X/V/24A1 - Bosch Rexroth R901572057

The ±10 V command input makes this version the match for controllers with a bipolar analogue output. The 4WREE10E1-50 carries 50 l/min nominal flow, passes up to 180 l/min maximum flow at peaks and holds 350 bar operating pressure. In mid position spool symbol E1 blocks all four ports.

Benefits

• ±10 V command value, wired straight to a bipolar analogue output of the controller
• 50 l/min nominal flow, up to 180 l/min maximum flow
• Spool symbol E1 blocks the centre, four ports, three switching positions
• FKM seals, HL hydraulic fluid, 7.3 kg unit weight
• Operating pressure up to 350 bar, subplate mounting to ISO 4401-05-04-0-05
• On-board digital electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804

Application

The valve goes into medium sized positioning and feed axes on machine tools, test rigs and special purpose machinery. A voltage command needs no burden resistor and can be applied straight from the analogue output. The closed centre prevents the axis from sagging while the pump is stopped.
