Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9K31/F1M - Bosch Rexroth R901486759

A voltage command loses accuracy over long cable runs, a current signal does not. This pilot-operated proportional directional valve in size 32 therefore works on 4 to 20 mA and converts it into 520 l/min nominal flow at up to 350 bar.

Key benefits

• Current command value of 4 to 20 mA into the on-board electronics, supplied with 24 V DC
• 520 l/min nominal flow, while size 32 carries up to 1600 l/min
• Operating pressure up to 350 bar, mounting pattern ISO 4401-10-09-0-05 with 4 ports
• External pilot oil supply and external pilot oil return keep the pilot stage clear of working pressure, no pressure reducing valve is fitted
• Spool symbol E1 with 3 switching positions and concealed manual override
• UKCA declaration on electromagnetic compatibility to SI2016/1091

Applications

Large presses, forging lines and rolling stands draw oil in this class. The current input pays off wherever the control cabinet sits far from the valve. The external pilot circuit has to stay pressurised, otherwise the pilot stage will not move.
