Directional Spool Valve 4WEH16HJ7X/6EG24N9S2K4/B10 - Bosch Rexroth R900947448

Pilot oil supply and pilot oil return both sit on the outside here, which decouples the pilot stage from whatever the main circuit does. The valve weighs 9.6 kg and carries the spool with symbol J in three switching positions. Across the subplate to ISO 4401-07-07-0-05 it passes up to 300 l/min at a maximum of 280 bar.

Benefits

• External pilot oil supply and external pilot oil return
• Mass of 9.6 kg in size 16
• Spool symbol J with three switching positions on four ports
• Flow up to 300 l/min, maximum operating pressure of 280 bar
• Subplate mounting to ISO 4401-07-07-0-05, solenoid actuation at 24 VDC
• 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL fluid

Application

Plants running on accumulators or idle circulation need a pilot stage that stays fed even when the main circuit loses pressure. This build therefore draws its pilot oil from a source of its own. Two additional lines have to be provided on the subplate.
