Directional Spool Valve 4WEH16D7X/6EG24N9S2K4 - Bosch Rexroth R900925313

The pilot-operated directional spool valve 4WEH16D7X/6EG24N9S2K4 weighs 10.46 kg and works with spool symbol D in size 16. It draws pilot oil from an external source and returns it externally, so the main circuit does not have to supply pressure for the switching stroke. Flow reaches 300 l/min at up to 280 bar maximum operating pressure.

Benefits

• 2 switching positions on spool symbol D across 4 ports
• External pilot oil supply and external pilot oil return, the valve still switches while the main circuit runs unloaded
• 300 l/min flow at 280 bar maximum operating pressure
• 10.46 kg weight, NBR seals matched to HL hydraulic fluid
• 24 VDC solenoid actuation, wired through a connector, 3-pole (2 + PE) according to EN 175301-803
• Subplate mounting to connection diagram ISO 4401-07-07-0-05

Application

Two switching positions are enough for axes that travel between two end stops and need no unloaded intermediate state. Because pilot supply and pilot return are routed apart from the working circuit, the valve also suits circuits with unloaded circulation or raised tank back pressure. Subplate mounting to ISO 4401-07-07-0-05 allows an exchange against identically coded size 16 builds.
