Proportional Directional Valve 4WRZ10W6-85-7X/6EG24ETK4/V - Bosch Rexroth R978910146

The spool to symbol W6 decides how this proportional valve links its 4 ports across 3 switching positions. At a nominal flow of 85 l/min, 170 l/min are possible at maximum. All sealing points use FKM, and the pilot stage works without a pressure reducing valve.

Benefits

• Symbol W6 in 3 switching positions across 4 ports
• Nominal flow 85 l/min, maximum flow 170 l/min
• FKM seals, mass 8.65 kg
• Internal pilot oil supply and internal pilot oil return
• Version without a pressure reducing valve in the pilot stage
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05

Applications
