Directional Spool Valve 4WEH16E7X/6EG24N9S2K4KSO8 - Bosch Rexroth R901139256

Pilot oil supply and return of this size 16 main stage both run through an external circuit. Control pressure therefore stays independent of the pressure and the return of the working circuit. The spool with symbol E switches three positions, the valve passes up to 300 l/min and holds 280 bar.

Benefits

• External pilot oil supply and external return, separate control circuit
• 300 l/min flow at 280 bar operating pressure
• Spool symbol E with three switching positions across four ports
• Subplate mounting to ISO 4401-07-07-0-05 in size 16
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) according to EN 175301-803
• 10.34 kg mass, NBR seals for HL hydraulic fluid

Application

The valve works in power units with their own control pressure supply, where switching time has to stay steady under a fluctuating working pressure. Size 16 covers cylinders up to 300 l/min. Interface and mounting follow ISO 4401-07-07-0-05.
