Directional Spool Valve H-4WEH25J6X/6EG24N9TS2K4/B08 - Bosch Rexroth R900729943

The internal pilot oil return saves one line at the subplate, while the supply still comes from the external control circuit. The pilot-operated size 25 main stage carries spool symbol J, works in three switching positions and passes up to 700 l/min at 350 bar.

Benefits

• External pilot oil supply with internal return, one control line fewer
• Spool symbol J with three switching positions across four ports
• 700 l/min flow at 350 bar operating pressure
• Subplate mounting to ISO 4401-08-08-0-05 in size 25
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
• 18.31 kg mass, NBR seals for HL hydraulic fluid

Application

This version fits power units with a secured control pressure supply and an unpressurised tank line. A flow of 700 l/min serves large press and lifting cylinders. The subplate only needs port X, because the pilot oil runs back into the tank line inside the valve.
