Proportional Directional Valve 4WRTE16E220L-4X/6EG24TK31/A1M - Bosch Rexroth R901424974

Not every plant needs both pilot lines brought outside. The 4WRTE16E220L-4X/6EG24TK31/A1M takes pilot pressure externally through the X line but returns the pilot oil internally, while providing 220 l/min nominal flow.

Benefits

• External pilot oil supply with internal return, only one extra line at the block.
• 220 l/min nominal flow, up to 460 l/min in size 16.
• Command value ±10 V through on-board electronics, supply 24 V DC.
• Spool symbol E, three switching positions, four ports.
• 11.22 kg weight at 350 bar maximum operating pressure, NBR seals.

Applications

This mixed arrangement suits control blocks with a clean tank return where only the pilot pressure comes from a separate circuit. It is used on presses, test benches and lifting gear. Connection diagram and mounting follow ISO 4401-07-07-0-05.
