Directional Spool Valve 4WEH10H4X/6EG24N9S2K4 - Bosch Rexroth R900976528

At 160 l/min a direct operated size 10 spool runs out of solenoid force, while a size 16 valve is larger than needed. The pilot-operated 4WEH10H4X/6EG24N9S2K4 covers exactly that band, fits a hole pattern to ISO 4401-05-05-0-05 and holds 280 bar.

Benefits

• Up to 160 l/min at a maximum of 280 bar in size 10 to ISO 4401-05-05-0-05.
• Spool symbol H in three switching positions across four ports.
• External pilot oil supply and external pilot oil return, pilot pressure comes from a separate circuit.
• Solenoid actuation at 24 VDC and a 3-pole connector (2 + PE) to EN 175301-803.
• 8.36 kg, NBR seals for HL hydraulic fluid.

Application

It controls medium sized cylinders in machine tools, presses and test rigs. Because pilot supply and drain are external, pilot pressure stays constant even when a working circuit is unloaded in its centre position.
