Directional Spool Valve 4WEH16J7X/6EG24N9SK4/10B08 - Bosch Rexroth R900947103

As soon as the main circuit can drop to zero pressure in service, an internally fed pilot stage loses its pilot pressure. This build therefore draws pilot oil from an external source and discharges it externally, keeping the pilot stage independent of what the main circuit does. The spool carries symbol J and the valve passes up to 300 l/min at a maximum of 280 bar.

Benefits

• External pilot oil supply and external pilot oil return, independent of the main circuit
• Spool symbol J in three switching positions on four ports
• Flow up to 300 l/min, maximum operating pressure 280 bar
• Size 16 with subplate mounting to ISO 4401-07-07-0-05
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• Mass 11.25 kg, NBR seals for HL hydraulic fluid

Application

Plants running accumulator charging or idle circulation, where main pressure disappears at times, are where this build belongs. Pilot pressure then comes from a small dedicated pump or from an accumulator. Both pilot lines are routed separately on the subplate.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16J7X/6EG24N9SK4/10B08 under material number R900947103. Data sheets RE 24751 and RE 07600-B carry the characteristic curves, the installation dimensions and the interface data. Check that your subplate provides ports X and Y for the external pilot oil path.
