Directional Spool Valve 4WEH16H7X/6EG24N9TK4/B08 - Bosch Rexroth R901339238

Flow of up to 300 l/min is what drives the choice of size 16 for the pilot-operated 4WEH16H7X/6EG24N9TK4/B08. Spool symbol H provides three switching positions across four ports at 280 bar maximum operating pressure. Pilot oil arrives from an external source and returns internally, and the valve weighs 9.7 kg.

Benefits

• 300 l/min flow as the rating limit of size 16
• Spool symbol H with 3 switching positions across 4 ports
• 280 bar maximum operating pressure, NBR seals for HL hydraulic fluid
• Mounting pattern ISO 4401-07-07-0-05, subplate mounting
• 24 VDC supply voltage, 3-pole connector (2 + PE) to EN 175301-803
• Weight 9.7 kg

Applications

The valve bolts onto a subplate to ISO 4401-07-07-0-05 and reverses cylinders that swallow large volumes. External pilot oil supply allows a separate control circuit whose pressure stays independent of the working pressure, while the return runs internally to the tank port. Account for the pressure drop across the valve at 300 l/min when sizing the circuit.
