Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R900736694

When working pressure temporarily falls below what the pilot stage requires, a valve without external supply simply stalls. The 4WRZE10W6-85-7X/6EG24N9TK31/F1D3M therefore takes its control oil from outside through the X port, returns it internally and meters 85 l/min nominal flow at up to 315 bar.

Benefits

• Size 10 with spool symbol W6, rated at 85 l/min nominal flow.
• Pilot oil arrives externally through the X port and returns internally.
• The built-in pressure reducing valve holds pilot pressure steady while the main circuit runs up to 315 bar.
• Command value input 4...20 mA on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• NBR seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.47 kg weight.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Technical data

Applications

This layout is wanted on axes with unloading phases, in forming lines with changing load and in circuits driven by a constant pressure pump. The 4...20 mA current command carries over long cable runs with little interference. No additional Y drain line has to be laid.
