Proportional Directional Valve 4WRTE27E500L-4X/6EG24K31/A1V - Bosch Rexroth R901469319

Without feedback of the spool position a residual error stays in the axis once flow gets high. The 4WRTE27E500L-4X/6EG24K31/A1V measures that position internally and converts a nominal command of 500 l/min at up to 270 bar operating pressure.

Benefits

• Internal position feedback - the spool follows the ±10 V command without a lasting offset.
• 500 l/min nominal flow, the valve copes with up to 1000 l/min.
• Symbol E in size 27 with a linear characteristic and three switching positions.
• External pilot oil supply and return keep the pilot stage working even at low system pressure.
• 19.45 kg, ISO 4401-08-07-0-05 interface, FKM seals, HL fluid.

Application

The valve serves forging presses, stretching lines and large test cylinders where the stroke has to be fast yet guided. On-board electronics on 24 VDC take the command straight from the controller. Wiring runs through a 7-pole connector (6 + PE).
