Directional Spool Valve 4WEH16D7X/6EG24N9DL/B10 - Bosch Rexroth R901302789

The 4WEH16D7X/6EG24N9DL/B10 redirects flows of up to 300 l/min across two switching positions. As a pilot operated size 16 spool valve with external pilot oil supply and external pilot oil return it works up to a maximum operating pressure of 280 bar.

Benefits

• External pilot oil supply and external pilot oil return keep switching reliable even when pressure in the main gallery fluctuates.
• Flow capacity of 300 l/min in size 16 for cylinders running at high piston speed.
• Spool symbol D with 2 switching positions and 4 ports for clearly defined end positions.
• Maximum operating pressure of 280 bar at a weight of 9.45 kg.
• Subplate mounting to ISO 4401-07-07-0-05 for interchange with standard size 16 valves.
• Solenoid actuation at 24 VDC, the standard control cabinet voltage.

Application

Typical consumers are press and lifting cylinders that swallow a lot of oil in a short time. External pilot supply pays off wherever pressure in the P gallery drops too low for the pilot stage from time to time, for instance in recirculation circuits. With 2 switching positions the control stays simple and the end positions are unambiguous.
