Directional Spool Valve 4WEH 10 E4X/6EG24N9DK35L - Bosch Rexroth R978035518

Between two working directions a control often needs a third, defined position. The pilot-operated 4WEH 10 E4X directional spool valve in size 10 provides it through symbol E, passes up to 160 l/min and works at operating pressures up to 280 bar.

Advantages

• Three switching positions to symbol E, the centre position sets the resting state of the drive.
• Up to 160 l/min at a maximum of 280 bar across four ports in the main circuit.
• Wiring through a connector, 4-pole, M12 x 1, coding A, matching prefabricated circular connectors already used in plant wiring.
• Hydraulic pilot stage with external pilot oil supply and external return, which keeps the switching function independent of main circuit pressure.
• Connection diagram ISO 4401-05-05-0-05 as a subplate mounting at 6.8 kg weight.
• NBR seals for HL hydraulic fluid and solenoid actuation at 24 VDC.

Application

The valve controls cylinders and hydraulic motors in machine tools, test rigs and power units of medium output. The third position to symbol E gives the drive a defined state between extend and retract, for example during a tool change or a pause in the cycle. The M12 connector with coding A simplifies wiring where the plant is already equipped with circular connectors.
