Directional Spool Valve 4WEH16D7X/6EG24N9EK4/B12P4,5 - Bosch Rexroth R900706826

Two valves sharing a spool symbol can differ clearly in their pilot stage, which is why the full type designation applies. The pilot-operated 4WEH16D7X/6EG24N9EK4/B12P4,5 works with internal pilot oil supply and external pilot oil return and routes up to 300 l/min at a maximum of 280 bar.

Benefits

• Identified unambiguously by material number R900706826 and type 4WEH16D7X/6EG24N9EK4/B12P4,5
• Two switching positions on spool symbol D, four ports
• Flow of up to 300 l/min at a maximum of 280 bar in size 16
• Internal pilot oil supply, external pilot oil return
• Weight of 9.5 kg, solenoid actuation at 24 VDC, NBR seals

Application

For maintenance it matters that replacement and old part agree in spool symbol, voltage and pilot oil routing. If one of those differs, the axis shifts other than intended. The valve sits on the subplate mounting to ISO 4401-07-07-0-05 in size 16 and runs on HL hydraulic fluid.
