Proportional Directional Valve 4WRZ25E1-325-7X/6EG24N9K4/V - Bosch Rexroth R900962403

Where a dedicated pilot pump exists, connecting the pilot stage externally on both sides is the sensible route. The 4WRZ25E1-325-7X/6EG24N9K4/V is built exactly that way, working with 325 l/min nominal flow, spool symbol E1 as well as 350 bar maximum operating pressure.

Benefits

• External pilot oil supply plus external pilot oil return, pilot stage fully separated from the working circuit
• Spool symbol E1 in size 25, connection diagram ISO 4401-08-08-0-05
• Nominal flow 325 l/min, maximum flow 870 l/min
• Maximum operating pressure 350 bar, 3 switching positions, 4 ports
