Directional Spool Valve 4WEH16HA7X/6EG24N9ETK4QM0G24/B10P4,5 - Bosch Rexroth R901525922

The 4WEH16HA7X/6EG24N9ETK4QM0G24/B10P4,5 is a pilot-operated size 16 directional spool valve for 300 l/min and a maximum operating pressure of 280 bar. Pilot oil is taken and returned internally, which removes the need for a separate pilot circuit. The solenoid runs on 24 VDC and the valve weighs 9.5 kg.

Benefits

• 300 l/min flow at 280 bar maximum operating pressure
• Internal pilot oil supply and internal pilot oil return, no separate pilot circuit required
• Spool symbol A with 2 switching positions on 4 ports
• ISO 4401-07-07-0-05 connection diagram, 9.5 kg
• 24 VDC supply voltage, 3-pole connector (2 + PE) to EN 175301-803

Application

Size 16 is used in machine tools, plastics machinery and mobile power units whenever the flow exceeds what size 10 can pass. Internal pilot control saves a dedicated pilot line but requires sufficient pressure at port P. The NBR seals match HL hydraulic fluid.
