Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9K31/F1D3V - Bosch Rexroth R901342141

Positioning and feed axes need a valve that releases oil along a characteristic curve rather than at a switching point. The 4WRZE10W8-50-7X/6EG24N9K31/F1D3V delivers 50 l/min nominal flow in size 10 at operating pressures up to 315 bar, peaking at 170 l/min.

Benefits

• 50 l/min nominal flow against a 170 l/min maximum - rapid traverse and fine feed from one frame size.
• Operating pressure up to 315 bar across all four ports of size 10.
• 4...20 mA setpoint input, immune to voltage drop over long signal runs.
• On-board electronics remove the need to fit a separate amplifier card in the cabinet.
• External pilot oil supply plus external pilot oil return keep the control circuit clear of fluctuating main pressure.
• Spool symbol W8, 3 switching positions, ISO 4401-05-05-0-05 interface, FKM seals rated for HL hydraulic fluid.

Technical data

Applications

Presses, injection moulding machines and test rigs benefit most, wherever an axis must ramp in gently before stopping without overshoot. Current signalling pays off when several metres separate valve from controller. External pilot supply suits plants that already run a pressure-regulated control oil circuit.
