Description
The H-4WEH25E6X/6EG24N9K4/P4,5 directional spool valve switches oil flow according to spool symbol E. In size 25 it carries up to 700 l/min at a maximum operating pressure of 350 bar across four ports and three switching positions.
Benefits
- Spool symbol E across three switching positions and four ports
- Flow up to 700 l/min, operating pressure up to 350 bar
- Subplate mounting to the ISO 4401-08-08-0-05 hole pattern, size 25
- External pilot oil supply and external pilot oil return
- Solenoid actuation at 24 VDC, NBR seals, weight 17.9 kg
Application
The valve controls lifting and lowering motion on presses, rolling mills and large power units. External pilot oil routing allows a separate supply for the pilot stage. Mounting requires a subplate to ISO 4401-08-08-0-05.
Manufacturer
Bosch Rexroth lists this valve under material number R901272850. Characteristic curves and switching times are given in the manufacturer datasheet.
