Proportional Directional Valve 4WRKE25W8-220P-3X/6EG24K31/F1D3M - Bosch Rexroth R901563105

Large axes should travel fast and still be finely adjustable around zero, and that is exactly what the linear characteristic curve with fine control range is made for. This pilot-operated size 25 proportional valve passes 220 l/min nominal flow, regulates the spool through internal position feedback and evaluates the 4...20 mA command value in its on-board electronics.

Benefits

• Linear characteristic curve with a fine control range, spool symbol W8
• 220 l/min nominal flow, up to 870 l/min across the valve
• 4...20 mA command value, 24 VDC supply, on-board electronics at the valve
• External pilot oil supply and external pilot oil return
• NBR seals for HL hydraulic fluid, operating pressure up to 350 bar
• Subplate mounting to ISO 4401-08-08-0-05, weight 17.8 kg

Applications

The valve regulates pressing force and position axes that alternate between rapid traverse and fine stroke. Subplate mounting to ISO 4401-08-08-0-05 allows replacement on existing size 25 manifolds. Supply and command value arrive through the 7-pole (6 + PE) connector to EN 175201-804.
