Directional Spool Valve 4WEH10D4X/6EG48N9S2K4 - Bosch Rexroth R901045085

A control cabinet level of 48 VDC calls for solenoids wound exactly for that voltage. This pilot-operated directional spool valve in size 10 switches two positions to symbol D, passes up to 160 l/min and works at a maximum operating pressure of 280 bar.

Benefits

• 160 l/min flow across the ISO 4401-05-05-0-05 interface in size 10
• 48 VDC supply voltage, so the solenoid fits an existing 48 V level without a converter
• External pilot oil supply and external pilot oil return, keeping the pilot circuit independent of the main circuit pressure
• Two switching positions to symbol D across four ports
• 280 bar maximum operating pressure with NBR seals for HL hydraulic fluid
• 7.84 kg on subplate mounting, so a replacement leaves the piping untouched

Applications

It serves presses, clamping fixtures and hydraulic power units whose control system is built around 48 VDC. The rating of 160 l/min covers cylinders of medium bore. External pilot oil supply keeps the valve able to switch even when the working pressure drops below the required pilot pressure for a while.
