Proportional Directional Valve 4WRKE25E220L-3X/6EG24ETK31/A1D3V - Bosch Rexroth R901156926

Large cylinder and press axes need directional control that copes with 220 l/min nominal flow without an upstream amplifier. This pilot-operated size 25 proportional valve manages that with on-board electronics and internal spool position feedback, so the spool follows the ±10 V command value even at 350 bar operating pressure.

Benefits

• 220 l/min nominal flow, while the valve itself passes up to 870 l/min
• The ±10 V command value is evaluated by the on-board electronics at the valve, so a separate amplifier card is not needed
• Spool symbol E with a linear characteristic curve and internal spool position feedback
• Operating pressure up to 350 bar, FKM seals for HL hydraulic fluid
• Internal pilot oil supply and internal pilot oil return, so the pilot ports need no external piping
• Subplate mounting to ISO 4401-08-08-0-05, weight 17.9 kg

Applications

Typical installations are presses, injection moulding machines and test rigs where a cylinder runs under position control at 220 l/min. The subplate mounting to ISO 4401-08-08-0-05 fits any size 25 manifold. Supply voltage of 24 VDC and the command signal reach the valve through the 7-pole (6 + PE) connector to EN 175201-804.
