Proportional Directional Valve 4WRZ32E520-7X/6EG24N9K4/V - Bosch Rexroth R900970738

If one central pilot circuit feeds several valve stations, every valve has to couple into it rather than tap internally. The 4WRZ32E520-7X/6EG24N9K4/V takes pilot oil from outside and returns it outside, at 520 l/min nominal flow in size 32.

Key benefits

• External pilot oil supply and external return for plants with a central pilot circuit.
• 520 l/min nominal flow, maximum flow 1600 l/min, operating pressure up to 350 bar.
• Spool symbol E, 3 switching positions, 4 ports, connection pattern ISO 4401-10-09-0-05.
• FKM seals, HL hydraulic fluid, 43.16 kg weight.
• Concealed manual override, version without pilot pressure reducing valve.
• External amplifier electronics, 24 VDC supply, 3-pole connector (2 + PE).

Technical data

Applications

Production lines in which one shared power unit serves several presses or hoists are the typical case. Because pilot pressure is generated centrally, all axes on the line behave alike. At 520 l/min nominal flow the valve also covers the larger cylinders in such lines.
