Proportional Directional Valve 4WRA10W30-2X/G24N9K4/V - Bosch Rexroth R900922441

Switching directional valves only know open and closed, which costs precision and loads the mechanics. This directly actuated proportional valve controls direction and rate steplessly, with 30 l/min nominal flow and up to 75 l/min of flow.

Benefits

• Nominal flow 30 l/min at a maximum flow of 75 l/min.
• Spool symbol W with 3 switching positions on 4 ports.
• Directly actuated, giving short response times without a pilot circuit.
• Electrical with external electronics, 24 VDC supply voltage, maximum operating pressure 315 bar.
• Concealed auxiliary actuation for emergency operation without control voltage.
• 5.92 kg weight, subplate mounting ISO 4401-05-04-0-05, FKM seals.

Application

The valve controls feed axes, clamping cylinders and hydraulic motors that have to start softly and position accurately. The external amplifier takes the command value from the control system and feeds the proportional solenoid. FKM seals and HL hydraulic fluid define the operating range.
