Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/F1M - Bosch Rexroth R901213530

The 4WRZE10W6-85-7X/6EG24N9EK31/F1M meters up to 85 l/min following the W6 spool symbol. Pilot oil is taken internally and returned externally, and no pressure reducing valve sits in the pilot stage.

Advantages

• W6 spool with 85 l/min nominal flow and up to 170 l/min maximum flow
• Operating pressure to 315 bar at a valve weight of 8.01 kg
• Internal pilot oil supply with external pilot oil return
• Concealed auxiliary actuation for commissioning and emergency movement
• 4 to 20 mA command value into the on-board electronics, 24 V DC supply
• UKCA under SI2016/1091, subplate mounting to ISO 4401-05-05-0-05

Applications

The plate goes onto manifolds of forming machines, lifting gear and power units feeding one consumer at around 85 l/min. An external pilot drain keeps return line back pressure away from the pilot stage. NBR seals cover HL oil.
