Proportional Directional Valve 4WRZ25W6-220-7X/6EG24N9K4/V - Bosch Rexroth R900947116

Handling at the manifold decides much of how long an exchange takes. The 4WRZ25W6-220-7X/6EG24N9K4/V weighs 11 kg, meters 220 l/min nominal flow and draws pilot oil from a circuit of its own.

Benefits

• 11 kg weight, mounted on the ISO 4401-08-08-0-05 interface in size 25.
• Pilot oil supplied and drained externally, the pilot circuit works independently.
• 220 l/min nominal flow within a maximum flow of 870 l/min.
• Spool symbol W6, 350 bar operating pressure, 3 switching positions across 4 ports.
• FKM seals, concealed auxiliary actuation, control at 24 VDC through external electronics.

Applications

The valve serves machines whose manifold sits in an awkward location and has to be fitted without lifting gear. Its own pilot circuit keeps switching times independent of load pressure. An internal pressure reducing valve is not included.
