Proportional Directional Valve 4WRTE16W6-220L-4X/6EG24ETK31/A1M - Bosch Rexroth R901437287

Higher throughput and defined behaviour in mid position do not exclude each other. The 4WRTE16W6-220L-4X/6EG24ETK31/A1M carries spool symbol W6 at 220 l/min nominal flow and accepts the command value as a ±10 V voltage.

Benefits

• 220 l/min nominal flow with spool symbol W6, up to 460 l/min maximum.
• Voltage command ±10 V through on-board electronics at 24 V DC.
• Internal pilot oil routing for supply and return, less piping at the block.
• 350 bar maximum operating pressure, connection diagram ISO 4401-07-07-0-05.
• 18.48 kg weight with NBR seals, hydraulic fluid HL.

Applications

The valve serves lifting and feed axes with large cylinder volumes, for example in forming presses and material testing machines. Internal spool position feedback keeps the characteristic stable under changing load. The mass of the valve should be taken into account when designing the manifold.
