Proportional Directional Valve 4WRZ32W8-520-7X/6EG24K4/M - Bosch Rexroth R901354494

A plant with a central pilot circuit and automatic operation needs neither a pilot branch nor a hand lever on the main valve. The 4WRZ32W8-520-7X/6EG24K4/M is built that way and controls 520 l/min nominal flow at a maximum of 350 bar.

Benefits

• External pilot oil supply and external return, pilot pressure and relief come from the central pilot circuit.
• Without auxiliary actuation, the spool follows the amplifier signal alone.
• 520 l/min nominal flow, throughput up to 1600 l/min in size 32.
• 37.52 kg weight, spool symbol W8, ISO 4401-10-09-0-05 pattern across 4 ports.
• 350 bar maximum operating pressure, NBR seals, intended for HL hydraulic fluid.

Applications

The valve serves automated press lines, stretching plants and lifting gear whose pilot circuit is built centrally. Because there is neither an internal branch nor a hand lever, the operating state stays clearly attributable to the controller. The electrical connection uses a 7-pole (6 + PE) plug to EN 175201-804.
