Directional Spool Valve 4WEH16D7X/6EG24N9EK4/B10P4,5 - Bosch Rexroth R900927439

Taking pilot oil from the pressure channel saves a supply line but calls for a channel that holds pressure during the shifting stroke as well. The pilot-operated 4WEH16D7X/6EG24N9EK4/B10P4,5 works that way and then returns pilot oil externally, at a flow of up to 300 l/min and a maximum of 280 bar.

Benefits

• Internal pilot oil supply, external pilot oil return into a dedicated line
• Two switching positions on spool symbol D across four ports
• Flow of up to 300 l/min at a maximum operating pressure of 280 bar
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
• Weight of 9.5 kg, subplate mounting to ISO 4401-07-07-0-05, NBR seals

Technical data

Application

The build suits circuits whose pressure channel is permanently fed and whose tank line carries back pressure. Pilot oil then goes to the reservoir separately and the reset stays defined. Typical places are manifolds on presses, lifting gear and machine tools running up to 300 l/min.
