Proportional Directional Valve 4WRKE16E220L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901565085

A press slide has to follow its path even when the load jumps as the tool enters the workpiece. The pilot-operated 4WRKE16E220L-3X/6EG24EK31/A1D3M passes 220 l/min nominal flow in size 16, holds up to 350 bar operating pressure and corrects spool position through internal feedback.

Benefits

• 220 l/min nominal flow, peaks up to 460 l/min maximum flow remain covered
• 350 bar operating pressure on the ISO 4401-07-07-0-05 pattern in size 16
• Internal pilot supply, external pilot drain, pilot pressure stays decoupled from the tank line
• ±10 V command value on the on-board electronics, no amplifier card in the cabinet
• Spool symbol E, NBR seals, 11.28 kg, matched to HL hydraulic fluid

Applications

The valve drives main axes of presses, die cushions and lifting gear that move large oil volumes each cycle. Subplate mounting in size 16 allows a direct swap against identical valves of the same pilot variant. Control needs only 24 VDC through the 7-pole plug to EN 175201-804.
