Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901079151

Every pilot line saved shortens assembly time, so this version needs neither an X nor a Y port because pilot oil supply and return both run internally, at 520 l/min nominal flow.

Key benefits

• Internal pilot oil supply and internal pilot oil return, only the working lines have to be connected at the valve.
• 36 kg installed mass on the ISO 4401-10-09-0-05 interface, clearly below the average for size 32.
• 520 l/min nominal flow at a permissible maximum flow of 1600 l/min.
• Spool symbol E1, 3 switching positions, 4 ports, ±10 V command value on a 24 VDC supply.
• Integrated pressure reducing valve up to 350 bar operating pressure, NBR seals for HL hydraulic fluid.

Applications

The version fits series machinery that takes pilot pressure from the main circuit and keeps the tank line unloaded. It noticeably shortens piping work inside the valve block. Electrical hookup is a 7-pole connector (6 + PE) to EN 175201-804.
