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

Technical data

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.
