Proportional Directional Valve 4WRAE6W15-2X/G24K31/A1V - Bosch Rexroth R900954077

A position controller with a voltage output can be wired to the valve without an intermediate converter. The 4WRAE6W15-2X/G24K31/A1V accepts a ±10 V command value, meters to spool symbol W and reaches 15 l/min nominal flow at a maximum flow of 42 l/min.

Benefits

• Command value ±10 V, taken straight from a bipolar controller output without a converter.
• Nominal flow of 15 l/min for steady positioning movements.
• Spool symbol W with 3 switching positions and 4 ports.
• On-board electronics at the valve, supply 24 VDC, mounting pattern ISO 4401-03-02-0-05.
• Operating pressure up to 315 bar at a mass of 2.2 kg.
• FKM seals for HL hydraulic fluid.

Applications

The valve works in closed-loop axes of test rigs and special purpose machines whose controller puts out a signed voltage. At zero command the spool rests in the centre position, so the control loop can be tuned around that zero point. FKM seals are fitted for mineral oil of class HL.
