Proportional Directional Valve 4WREE10E1-50-3X/M/24F1 - Bosch Rexroth R901576158

Not every axis needs 25 or 75 l/min, many fall in between. The 4WREE10E1-50 serves that gap with 50 l/min nominal flow, releases up to 180 l/min maximum flow at peaks and works at up to 350 bar. Spool symbol E1 blocks all four ports in mid position and the seals are NBR.

Benefits

• 50 l/min nominal flow as the middle step, up to 180 l/min maximum flow
• Spool symbol E1 with a closed centre, three switching positions, four ports
• 4...20 mA command value, on-board digital electronics, 24 VDC supply
• NBR seals for HL hydraulic fluid, 7.4 kg unit weight
• Operating pressure up to 350 bar, hole pattern ISO 4401-05-04-0-05
• 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity for EMC SI2016/1091

Technical data

Application

The middle flow step suits feed axes on machine tools, presses and test rigs whose cylinders are neither very small nor very fast. Because the valve is direct operated, the circuit needs no separate control oil supply. The closed centre keeps the axis in position at standstill.
