Proportional Directional Valve 4WRZ16W8-180-7X/6EG24N9ETK4/D3V - Bosch Rexroth R901478394

Nominal flow decides the balance between control quality and oil demand. The 4WRZ16W8-180-7X/6EG24N9ETK4/D3V is rated at 180 l/min and routes its pilot oil entirely internally, at 11.2 kg weight.

Benefits

• 180 l/min nominal flow, up to 460 l/min peak flow in size 16.
• Pilot oil supplied and returned internally, pilot stage with pressure reducing valve.
• 350 bar maximum operating pressure, ISO 4401-07-07-0-05 pattern.
• Electrical with external electronics, 24 VDC supply voltage.
• 11.2 kg weight, FKM seals for HL hydraulic fluid, concealed auxiliary actuation.

Applications

The valve is used on presses, injection moulding machines and test rigs with controlled main axes. Higher nominal flow shortens travel time on long cylinder strokes while the control structure stays the same. The external electronics sit in the cabinet and remain accessible for diagnosis and replacement.
