Proportional Directional Valve 4WRTE32E1-600L-4X/6EG24EK31/A1M - Bosch Rexroth R900954300

When the hydraulic schematic calls out symbol E1, the replacement valve has to match exactly that version. The 4WRTE32E1-600L-4X/6EG24EK31/A1M does so in size 32, works at a nominal flow of 600 l/min under 350 bar and accepts a command value of plus or minus 10 V at its on-board electronics.

Benefits

• Spool symbol E1 with 3 switching positions lets the existing circuit diagram stay unchanged.
• Nominal flow of 600 l/min within a maximum flow of 1600 l/min covers large cylinder areas.
• Internal pilot oil supply saves one line, while the external pilot oil return relieves the tank port at 350 bar operating pressure.
• Spool position feedback inside the valve keeps flow tied to the plus or minus 10 V command even when the load changes.
• Mounting pattern ISO 4401-10-09-0-05, 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, weight 37.21 kg.

Technical data

Applications

The valve goes into presses, lift tables and large handling axes where the cylinder must stand still in a defined mid position. An external pilot oil return pays off wherever the tank port sees back pressure from return filters or coolers. The fluid is mineral oil of class HL, the seals are NBR.
