Directional Spool Valve 4WEH16W7X/6EG24N9ETS2K4/B10 - Bosch Rexroth R901211924

From size 16 upwards, the way 300 l/min is reversed decides how the whole system is loaded. The 4WEH16W7X/6EG24N9ETS2K4/B10 carries this flow with a pilot stage, so the 24 VDC solenoid only has to switch the pilot valve.

Benefits

• 300 l/min flow in size 16, connection diagram ISO 4401-07-07-0-05.
• Pilot-operated design, the solenoid moves the pilot valve instead of the main spool.
• Spool symbol W with 3 switching positions on 4 ports.
• Internal pilot oil supply and internal pilot oil return, without extra piping.
• 280 bar maximum operating pressure at a weight of 10.78 kg.
• 24 VDC supply voltage through a connector, 3-pole (2 + PE) according to EN 175301-803.

Applications

Typical installations are hoists, press drives and large cylinder axes where the 300 l/min are actually called for. The subplate mounting to ISO 4401-07-07-0-05 allows assembly on existing control blocks. Internal pilot oil routing keeps the piping effort small, and the NBR seals suit HL hydraulic fluid.
