Directional Spool Valve 4WEH16E7X/6EG48N9SK4 - Bosch Rexroth R900933885

On the 4WEH16E7X/6EG48N9SK4 both supply and drain of the pilot oil run through ports of their own, which keeps the pilot stage separate from the working circuit. The valve handles 300 l/min at 280 bar maximum operating pressure, carries spool symbol E and weighs 10.92 kg.

Benefits

• Fully external pilot oil routing, pilot pressure independent of port P
• Spool symbol E with 3 switching positions across 4 ports
• 300 l/min at 280 bar maximum operating pressure in size 16
• 48 VDC supply voltage, 10.92 kg
• ISO 4401-07-07-0-05 hole pattern, NBR seals, HL hydraulic fluid

Application

The version is used in circuits with accumulator charging, unloading logic or widely varying system pressure. Because pilot oil comes from a source of its own, switching times stay the same across the whole cycle. The 48 V coil suits plants running that control level.
