Directional Spool Valve H-4WEH25D6X/6EG24N9K4/P4,5 - Bosch Rexroth R900936772

In size 25 the H-4WEH25D6X/6EG24N9K4/P4,5 passes 700 l/min and holds a maximum operating pressure of 350 bar. It is pilot-operated, switches on 24 VDC and weighs 17.66 kg. Pilot oil is fed in and drained externally.

Benefits

• 700 l/min at 350 bar, spool symbol D, size 25
• Pilot control from an external pilot circuit, independent of working pressure at port P
• 2 switching positions on 4 ports, ISO 4401-08-08-0-05 connection diagram
• 17.66 kg, NBR seals, HL hydraulic fluid
• 24 VDC supply voltage through a 3-pole connector (2 + PE)

Application

The valve controls large double-acting cylinders and hydraulic motors in presses, rolling mills and lifting gear. Where several consumers are fed from one pump, external pilot oil supply keeps switching times steady even when system pressure fluctuates. Swapping it against an identically coded predecessor needs no change to the piping.
