Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R900747754

Underground or in processing plants the mounting positions are awkward, while cable runs are long. The 4WRZE32W6-520-7X therefore needs no external control lines, taking its command as a 4 to 20 mA current signal at 520 l/min under 350 bar.

Benefits

• Fully internal pilot circuit keeps supply as well as return inside the valve, no extra piping.
• 4 to 20 mA current command shrugs off long cable runs, supply 24 VDC.
• 520 l/min nominal flow in size 32, flow up to 1600 l/min.
• Spool symbol W6, three switching positions, four ports.
• 350 bar operating pressure with NBR seals on HL hydraulic fluid, 43.92 kg.
• ISO 4401-10-09-0-05 subplate mounting, 7-pole connector (6 + PE) to EN 175201-804.

Application

Crushers, screening plants or hoists in processing run with system pressure permanently applied, which is what internal piloting requires. The small number of connections shortens installation plus servicing at awkward locations. Concealed auxiliary actuation moves the axis without any electrical supply.
