Directional Spool Valve 4WEH16Y7X/6EG24N9EK4/B10P4,5 - Bosch Rexroth R901254906

A return filter or a long tank run builds back pressure that upsets the reset of the pilot stage. The pilot-operated 4WEH16Y7X/6EG24N9EK4/B10P4,5 avoids that with internal pilot oil supply and external pilot oil return, routing up to 300 l/min at a maximum of 280 bar.

Benefits

• Internal pilot oil supply from the pressure channel, external pilot oil return in its own line
• Two switching positions on spool symbol Y across four ports
• Flow of up to 300 l/min, maximum operating pressure 280 bar
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
• Weight of 9.4 kg in size 16, subplate mounting to ISO 4401-07-07-0-05

Application

The combination suits plants with a return filter, an oil cooler or a long tank line where return pressure cannot be ignored. The separate pilot return keeps the pilot stage clear of it. Because pilot oil comes from the pressure channel, a second supply line on the manifold is not needed.
