Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9TK4/D3M - Bosch Rexroth R901328639

Too large a nominal flow makes control coarse, too small a one limits speed. The 4WRZ10E1-85-7X/6EG24N9TK4/D3M sits at 85 l/min nominal flow in size 10 and permits up to 170 l/min.

Benefits

• 85 l/min nominal flow, 170 l/min maximum flow, headroom for rapid traverse phases.
• 315 bar operating pressure with spool symbol E1 and 3 switching positions across 4 ports.
• External pilot oil supply, internal return, with a pressure reducing valve in the pilot stage.
• Electrical with external electronics, driven from an amplifier card, 24 VDC supply.
• 8.24 kg, NBR seals, HL fluid, 7-pole plug (6 + PE) to EN 175201-804.

Applications

The valve is intended for feed and press axes that have to accelerate and position evenly. Concealed auxiliary actuation allows the axis to be moved if the electronics fail. Through subplate mounting to ISO 4401-05-05-0-05 it fits any standard size 10 manifold.
