Proportional Directional Valve 4WRZE32W8-520-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900949577

The fewer control lines a power unit needs, the shorter the assembly work and the fewer potential leak points. This version of the 4WRZE32W8-520-7X manages with internal piloting in both directions and still reaches 520 l/min nominal flow.

Key benefits

• Internal pilot oil supply and internal return, with no external control lines and no pilot pump.
• 520 l/min nominal flow, and the flow may rise to 1600 l/min.
• The integrated pressure reducing valve limits pilot pressure independently of working pressure up to 350 bar.
• Spool symbol W8, three switching positions, four ports, subplate mounting to ISO 4401-10-09-0-05.
• A 4 to 20 mA command at the integrated electronics, 24 VDC supply through a 7-pole connector (6 + PE).

Applications

The valve is built for compact power units on presses, clamping devices and hoists where every additional port costs space. The 4 to 20 mA current command stays stable even over long cable runs inside the machine frame. A swap against an existing size 32 valve works without changing the subplate.
