Proportional Directional Valve 4WRZE10W9-50-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901035429

Over long cable runs a voltage command loses accuracy. This proportional directional valve of the 4WRZ(E) range therefore takes a 4...20 mA current command and converts it into 50 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• 50 l/min nominal flow in size 10, against a range maximum flow of 170 l/min.
• The 4...20 mA current command stays stable over long lines, electronics fed by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Internal pilot oil supply and internal pilot oil return save two drillings in the manifold.
• The built-in pressure reducing valve keeps pilot pressure constant regardless of a working pressure of up to 315 bar.
• Concealed auxiliary actuation moves the spool even when the electronics are dead, mounting pattern ISO 4401-05-05-0-05, weight 9.12 kg.

Applications

The valve controls feed axes on machine tools, clamping units of injection moulding machines and lifting gear in plant engineering. At 50 l/min nominal flow the resolution in the lower signal range stays fine enough for positioning moves. NBR seals suit mineral oil of class HL.
