Directional Spool Valve 4WEH32HD6X/OF6EG24N9K4 - Bosch Rexroth R901083994

When the main circuit can drop to zero pressure during operation, the pilot stage must not depend on it. The 4WEH32HD6X/OF6EG24N9K4 draws its pilot oil externally and discharges it the same way, at 1100 l/min throughput in size 32.

Benefits

• External pilot oil supply and external return, independent of the pressure in the main circuit.
• 1100 l/min at 280 bar across 4 ports, spool symbol D.
• 2 switching positions, a pilot-operated spool valve with solenoid actuation at 24 VDC.
• Subplate mounting ISO 4401-10-09-0-05 in size 32.
• 35 kg weight, NBR seals, HL fluid, electrically connected through a plug to EN 175301-803.

Applications

It is intended for circuits whose pump pressure is temporarily lowered or removed altogether, for example in idle-circulation schemes and accumulator operation. The external pilot oil then comes from a small dedicated pump or from the accumulator. Switching capability is retained even while the main circuit is unloaded.
