Directional Spool Valve H-4WEH25D6X/6EG24NTK4/B10 - Bosch Rexroth R901136351

From size 25 upwards the solenoid force is no longer enough to move the spool against 700 l/min. This directional spool valve therefore works pilot-operated and switches the oil flow direction to symbol D at up to 350 bar.

Benefits

• Flow up to 700 l/min in size 25, maximum operating pressure 350 bar.
• External pilot oil supply with internal pilot oil return, suited to circuits without permanent pressure at port P.
• Spool symbol D with 4 ports and 2 switching positions.
• Subplate mounting to ISO 4401-08-08-0-05, solenoid actuation at 24 VDC.
• 17.54 kg weight, NBR seals, HL hydraulic fluid.

Application

The valve controls large cylinders and hydraulic motors in presses, rolling mills and lifting gear. External pilot oil supply keeps it working even when system pressure at port P collapses for a while. The 3-pole connector (2 + PE) to EN 175301-803 keeps the wiring simple.
