Proportional Directional Valve 4WRKE25E220L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901186823

Back pressure from the return circuit shifts the working point of the pilot stage. The 4WRKE25E220L-3X/6EG24EK31/F1D3M therefore leads the pilot return away separately, while the supply comes internally from system pressure.

Benefits

• External pilot oil return, independent of back pressure in the tank circuit
• Internal pilot oil supply, no dedicated pressure line to the pilot stage
• Nominal flow 220 l/min, maximum flow 870 l/min
• 4...20 mA command value, linear characteristic curve, internal spool position feedback
• Maximum operating pressure 350 bar, spool symbol E

Application

For plants with return filters or long return lines where back pressure builds up. The 220 l/min nominal flow suits medium to large cylinders in size 25. Weight 18 kg, hydraulic fluid HL.
