Directional Spool Valve 4WEH16R7X/6EG24N9EK4/10B10 - Bosch Rexroth R901381527

On the 4WEH16R7X/6EG24N9EK4/10B10 the pilot oil is taken from the main circuit while the pilot oil return is led away externally. That combination keeps a defined tank pressure in the pilot circuit while the size 16 main stage passes up to 300 l/min across three switching positions.

Advantages

• Internal pilot oil supply, external pilot oil return
• Pilot-operated spool valve for flows up to 300 l/min
• Three switching positions to symbol R, four ports
• Operating pressure up to 280 bar in size 16
• Solenoids 24 V DC, 3-pole connector (2 + PE) to EN 175301-803
• Porting pattern ISO 4401-07-07-0-05, NBR seals

Application

The valve controls main drives in presses, injection moulding machines and lifting gear whose cylinders need large oil volumes. External pilot oil return makes sense when back pressure builds up in the return line of the main circuit. At 10.26 kg the valve is mounted on a size 16 subplate.
