Proportional Directional Valve 4WRTE16W6-220L-4X/6EG24K31/F1M - Bosch Rexroth R901475077

Two design questions meet in this valve, the behaviour in mid position and the source of the pilot oil. The 4WRTE16W6-220L-4X/6EG24K31/F1M answers both with symbol W6 and external pilot oil supply and return, at 220 l/min nominal flow.

Benefits

• Spool symbol W6 combined with external pilot oil supply.
• 220 l/min nominal flow, up to 460 l/min at peak.
• Current command 4 to 20 mA, on-board electronics at 24 V DC.
• 350 bar maximum operating pressure, connection diagram ISO 4401-07-07-0-05.
• 11.8 kg weight, NBR seals, hydraulic fluid HL.

Applications

The valve is intended for axes in presses and test benches whose system pressure collapses during the cycle and which also require defined behaviour in mid position. Pilot pressure arrives through the X line from a separate circuit. Four ports serve a double acting cylinder.
