Proportional Directional Valve 4WRTE32E400L-4X/6EG24K31/F1M - Bosch Rexroth R901238652

A closed-loop axis needs to know where the control spool actually stands. The 4WRTE32E400L-4X/6EG24K31/F1M measures spool position internally and feeds it back inside the valve while metering 400 l/min nominal flow at up to 350 bar operating pressure.

Benefits

• Internal spool position feedback inside the closed control loop of the valve, spool symbol E with a linear characteristic curve.
• 400 l/min nominal flow with a maximum flow of 1600 l/min across four ports.
• Maximum operating pressure 350 bar, connection diagram ISO 4401-10-09-0-05 for subplate mounting in size 32.
• 4...20 mA command value as a current signal that stays immune to interference over longer cable runs, processed by the on-board electronics on 24 VDC.
• External pilot oil supply and external pilot oil return, so the pilot stage can be fed from a circuit of its own.
• 35 kg valve weight, NBR seals and HL hydraulic fluid, 3 switching positions.

Applications

Typical duties are position-controlled cylinder axes in forming machines, material testing machines and simulation rigs, where the controller sets a position or a speed and the valve closes the inner loop. External piloting suits installations that already run a separate pilot circuit with filtered oil. The 7-pole connector (6 + PE) according to EN 175201-804 carries supply and command value in one cable.
