Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R900705138

An axis at 85 l/min, driven by a current signal and without a separate pilot circuit. That is what the 4WRZE10W6-85-7X/6EG24N9ETK31/F1D3M delivers, with internal pilot supply, internal return, a built-in pressure reducing valve and a 4...20 mA command input at up to 315 bar.

Benefits

• 3 switching positions and 4 ports at 85 l/min nominal flow, spool symbol W6.
• Pilot oil is taken internally and returned internally, so no separate X and Y line is needed.
• The built-in pressure reducing valve holds pilot pressure steady while the main circuit runs up to 315 bar.
• The 4...20 mA command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, NBR seals for HL fluid, 170 l/min maximum flow at 9.18 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

Valves like this sit in presses, sawing lines and test rigs with long signal paths between controller and manifold. The current signal stays immune to voltage drop along the cable. Because both pilot paths run internally, a standard subplate is enough.
