Directional Spool Valve 4WEH16HD7X/OF6EG24N9ETS2K4/B10 - Bosch Rexroth R900956551

Four working ports and one solenoid cable are enough once the pilot stage draws its oil internally from port P and returns it internally to port T. The 4WEH16HD7X/OF6EG24N9ETS2K4/B10 is arranged in that way and directs up to 300 l/min at a maximum of 280 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no extra pilot line on the control block.
• Up to 300 l/min flow at a maximum operating pressure of 280 bar.
• Spool symbol D with two switching positions, solenoid actuation at 24 VDC.
• Four ports to ISO 4401-07-07-0-05 in size 16 subplate mounting.
• 10.86 kg weight, NBR seals for HL hydraulic fluid.

Applications

Typical mounting points are compact control blocks on presses, clamping equipment and lifting gear where no separate pilot supply exists. The condition is a system pressure at port P that feeds the pilot stage reliably, together with a tank line carrying little back pressure. Electrical hook-up uses a connector, 3-pole (2 + PE) to EN 175301-803.
