Directional Spool Valve H-4WEH25HC6X/OF6EG24N9K4 - Bosch Rexroth R900940702

The H-4WEH25HC6X suits circuits reversing up to 700 l/min. External pilot oil supply and external pilot oil return separate the pilot stage from the main circuit, which keeps switching conditions clean at 350 bar.

Benefits

• Rated throughput up to 700 l/min in size 25
• Operating pressure up to 350 bar across four ports
• Two switching positions to spool symbol C
• External pilot oil supply and external pilot oil return
• Mounting pattern ISO 4401-08-08-0-05, weight 17.5 kg
• 24 VDC through a connector 3-pole (2 + PE) to EN 175301-803

Application

Typical duties are large presses, rolling mill hydraulics and marine or stage engineering with high flow rates. External pilot supply pays off when the main circuit should idle unpressurised while the pilot stage still needs pressure. NBR seals match HL fluid.

Manufacturer

The material number is R900940702. Data sheet RE 24751 carries the curves and pilot oil demand, RE 07600-B gives the range overview.
