Proportional Directional Valve 4WRZE25W6-220-7X/6EG24EK31/F1D3M - Bosch Rexroth R901051672

Frequency converters and long cable routes trouble a voltage line, while a current signal shrugs them off. The 4WRZE25W6-220-7X/6EG24EK31/F1D3M accepts a 4...20 mA command, draws its pilot oil internally and discharges it through an external return, at 220 l/min nominal flow.

Benefits

• A 4...20 mA command keeps its integrity next to converters and contactors.
• Internal pilot oil supply with external return needs only one extra line.
• Spool symbol W6 with 3 switching positions and 220 l/min nominal flow in size 25.
• A built-in pressure reducing valve holds pilot pressure constant up to 350 bar working pressure.
• UKCA conformity to SI2016/1091, NBR seals, weight 20.74 kg.

Applications

The valve serves forming lines and materials handling where drives and hydraulics share one cabinet. An external pilot return prevents back pressure in the tank line from shifting the control. NBR seals are fitted for mineral oil of class HL.
