Directional Spool Valve 4WEH16R7X/6EG24N9S2K4K - Bosch Rexroth R900707444

A control block can only be extended cleanly when interface pattern and spool symbol agree. Pilot-operated directional spool valve 4WEH16R7X/6EG24N9S2K4K supplies symbol R on the ISO 4401-07-07-0-05 interface and passes up to 300 l/min.

Benefits

• Spool symbol R, three switching positions over four ports, subplate mounting.
• 300 l/min at a maximum of 280 bar operating pressure.
• External pilot oil supply, external pilot oil return, the pilot circuit is fed separately.
• 24 V DC solenoid actuation, connector 3-pole (2 + PE).
• 10.92 kg, NBR seals, HL hydraulic fluid.

Application

The valve serves power units of forming machines and test rigs where several actuators share one block. Because pilot oil is fed and returned externally, switching stays stable even when main pressure drops away. The ISO 4401-07-07-0-05 pattern is standardised, so no subplate rework is needed.

Manufacturer

Bosch Rexroth lists this pilot-operated directional spool valve 4WEH16R7X/6EG24N9S2K4K under material number R900707444. Data sheets RE 24751 and RE 07600-B show characteristic curves, installation dimensions and connection diagram. Symbol R identifies the mid position of this version, while the material number stays the unambiguous ordering reference.
