Proportional Directional Valve 4WRKE25W6-350L-3X/6EG24EK31/F1D3V - Bosch Rexroth R901363247

Rapid traverse and pressing stroke place opposite demands on the same valve. The 4WRKE25W6-350L-3X/6EG24EK31/F1D3V answers that with 350 l/min rated flow, a linear characteristic and internal piston position feedback, at an operating limit of 350 bar.

Benefits

• Linear characteristic and internal piston position feedback for even behaviour across the stroke.
• 350 l/min rated flow, flow up to 870 l/min, operating limit 350 bar.
• Internal pilot oil supply with external pilot oil return, pilot operated spool.
• Spool symbol W6, three switching positions, ISO 4401-08-08-0-05 pattern in size 25.
• Current command value 4...20 mA, 24 VDC supply, 17.88 kg, FKM seals for HL fluid.

Application

Main cylinders on forming and forging presses, draw cushions and heavy lifting axes use this valve. The external pilot oil return keeps the pilot stage clear of tank line back pressure when large oil volumes flow back. For axes with less demand, the version rated at 220 l/min is available.
