Proportional Directional Valve 4WRKE32R3-400L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901337457

A smaller nominal flow across the same signal range means finer steps at the cylinder. The 4WRKE32R3-400L-3X/6EG24ETK31/F1D3M turns 4 to 20 mA into 400 l/min, supplies its pilot stage internally and allows up to 350 bar operating pressure.

Benefits

• 400 l/min nominal flow in size 32, finer metering than the larger stages of the same series.
• Internal pilot oil supply with internal return, no separate pilot circuit required.
• Command value 4 to 20 mA at the on-board electronics on 24 V DC.
• Spool symbol R3 with a linear characteristic across three switching positions.
• NBR seals, 37.4 kg, connection diagram ISO 4401-10-09-0-05, peak flow 1550 l/min.

Technical data

Applications

The stage is called for where a large axis has to travel slowly at high accuracy, such as closing a press tool. Four ports on subplate mounting keep installation within the size 32 footprint. Spool position is fed back internally.
