Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R900730910

Low mass and little pipework come together here, because at 42.2 kg pilot oil supply and return run internally while 520 l/min nominal flow remains available.

Key benefits

• 42.2 kg installed mass on the ISO 4401-10-09-0-05 interface, helpful for service and replacement.
• Pilot oil supplied and returned internally, extra pilot lines are unnecessary.
• 520 l/min nominal flow in a body rated for a maximum flow of 1600 l/min.
• ±10 V command value on 24 VDC, spool symbol W8 with 3 switching positions and 4 ports.
• Integrated pressure reducing valve to 350 bar operating pressure, NBR seals for HL hydraulic fluid.

Applications

Machine tools, injection moulding machines and power units with a densely packed valve block are the typical installation. The lower mass makes removal during service work easier. Electrical hookup is a 7-pole connector (6 + PE) to EN 175201-804.
