Directional Spool Valve 4WEH 10 G4X/6EG24N9DAL - Bosch Rexroth R978901259

The 4WEH 10 G4X/6EG24N9DAL switches the direction of oil flow in circuits up to 160 l/min, working with external pilot oil supply and external pilot oil return. The electrical side comes in through a cable gland and the solenoid runs on 24 VDC. This pilot-operated spool valve in size 10 holds 280 bar maximum operating pressure and mounts to pattern ISO 4401-05-05-0-05. Spool symbol G spreads four ports over three switching positions and the weight is 6.8 kg.

Benefits

• 160 l/min flow in size 10
• 280 bar maximum operating pressure on a pilot-operated spool valve
• Spool symbol G with 3 switching positions and 4 ports
• Mounting pattern ISO 4401-05-05-0-05, subplate mounting
• 24 VDC solenoid, electrical connection through a cable gland
• NBR seals for HL hydraulic fluid, weight 6.8 kg

Applications

External pilot supply calls for a separate control oil line, in return the pilot pressure stays independent of the load pressure in the main circuit. Machine tools and presses switching up to 160 l/min are the usual case. With three switching positions, spool symbol G decides how the four ports behave in mid position, which has to be checked when the circuit is laid out.
