Directional Spool Valve 4WEH16HD7X/6EG24N9TK4/10 - Bosch Rexroth R900929122

This build takes pilot oil from a dedicated line but returns it internally into the tank port of the main stage. That saves one pipe run while keeping pilot pressure independent of working pressure. The main flow reaches 300 l/min.

Benefits

• External pilot oil supply keeps pilot pressure independent of working pressure
• Internal pilot oil return, so a dedicated return line is not needed
• Two switching positions to symbol D across four ports
• 300 l/min in size 16 to the ISO 4401-07-07-0-05 interface
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Operating pressure up to 280 bar, NBR seals, weight 9.72 kg

Applications

This combination suits power units with their own pilot oil supply and low tank back pressure. It needs one control line fewer than a fully external build. The valve mounts on a standard size 16 subplate.
