Proportional Directional Valve 4WRA10E1-60-2X/G24N9K4/V - Bosch Rexroth R900908978

This valve controls the speed and the direction of an actuator steplessly. With a nominal flow of 60 l/min it passes up to 75 l/min, and the operating pressure reaches 315 bar. The spool is directly actuated while external electronics handle the control signal.

Benefits

• 60 l/min nominal flow and up to 75 l/min at 315 bar
• Direct actuation without a pilot stage, which keeps the response path short
• Spool symbol E1 with three switching positions, size 10 to ISO 4401-05-04-0-05
• Electrical with external electronics, 24 V DC, connector 3-pole (2 + PE)
• FKM seals and 5.9 kg weight

Application

It fits wherever a cylinder has to start and stop gently, for example in feed axes and handling equipment. The concealed auxiliary actuation allows movement when no voltage is present. FKM seals widen the choice of hydraulic fluid compared with NBR.
