Directional Spool Valve 4WEH16E7X/6EG24N9K4/10 - Bosch Rexroth R900949207

When an axis needs a defined rest position on top of advance and return, two switching positions are not enough. The pilot-operated directional spool valve 4WEH16E7X/6EG24N9K4/10 provides 3 switching positions on spool symbol E and passes up to 300 l/min at 280 bar maximum operating pressure in size 16.

Benefits

• 3 switching positions on spool symbol E across 4 ports
• External pilot oil supply and external pilot oil return, so the pilot stage works independently of pressure in the working circuit
• 300 l/min flow at 280 bar maximum operating pressure
• 24 VDC solenoid actuation, wired through a connector, 3-pole (2 + PE) according to EN 175301-803
• 10.3 kg weight, NBR seals matched to HL hydraulic fluid
• Subplate mounting to connection diagram ISO 4401-07-07-0-05

Technical data

Application

The third position is needed when a cylinder has to stand in a clearly defined state between two working strokes. Presses, lifting tables and machine tools run the valve in the main circuit while a separate pilot line feeds the pilot stage. For a replacement the connection diagram ISO 4401-07-07-0-05 is what counts, the valve fits existing size 16 subplates.
