Proportional Directional Valve 4WRKE32E1-600L-3X/6EG24EK31/F1D3V - Bosch Rexroth R901218348

Filters and coolers in the return line create back pressure that upsets an internally drained pilot stage. The 4WRKE32E1-600L-3X/6EG24EK31/F1D3V therefore takes its pilot return outside and controls 600 l/min nominal flow at 350 bar.

Benefits

• External pilot oil return, unaffected by back pressure from filters or coolers.
• Internal pilot oil supply, so no dedicated pilot pump is needed.
• 600 l/min nominal flow, 1600 l/min maximum in size 32.
• Command value 4 to 20 mA at the on-board electronics on 24 VDC.
• Symbol E1 at 350 bar, 36.94 kg weight, FKM seals, HL hydraulic fluid.

Application

Typical hosts are large power units with a shared return line where several axes discharge at once. The separate return keeps the pilot zero point stable and with it the positioning accuracy. Symbol E1 leaves the existing plant circuit unchanged.
