Proportional Directional Valve 4WRZE32E520-7X/6EG24N9TK31/F1D3V - Bosch Rexroth R900958046

When pilot control is fed from a separate circuit but the pilot return should stay inside the valve, the combination of external pilot oil supply and internal pilot oil return is the right one. The 4WRZE32E520-7X/6EG24N9TK31/F1D3V converts the 4 to 20 mA current signal into up to 520 l/min.

Benefits

• External pilot oil supply with internal pilot oil return, one control port fewer than the fully external version
• 4 to 20 mA command, safer against wire break than a voltage signal
• 520 l/min nominal flow, max. flow 1600 l/min
• Spool symbol E, max. operating pressure 350 bar
• 24 V DC, 7-pole connector (6 + PE) to EN 175201-804
• Weight 43.6 kg, interface ISO 4401-10-09-0-05

Applications

Used in test benches, rolling mill hydraulics and press drives with a separate pilot pump. The current signal pays off when the control cabinet sits far from the valve or drives work nearby. The 350 bar operating pressure also covers accumulator circuits.
