Proportional Directional Valve 4WRZ25W6-325-7X/6EG24N9EK4/M - Bosch Rexroth R900977993

A pilot-operated proportional directional valve only drops into an existing manifold when the spool symbol and the pilot oil path agree. The 4WRZ25W6-325-7X/6EG24N9EK4/M carries symbol W6 at 325 l/min nominal flow, the pilot supply is internal and the return is external.

Benefits

• Spool symbol W6, 3 switching positions, 325 l/min nominal flow
• Internal pilot oil supply, external pilot oil return, no pressure reducing valve
• Flow up to 870 l/min, maximum operating pressure 350 bar
• ISO 4401-08-08-0-05 interface in size 25, subplate mounting
• Driven by external electronics, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804
• Concealed auxiliary actuation for commissioning

Applications

For presses, injection moulding machines and test rigs whose main axis calls for around 325 l/min at system pressures up to 350 bar. The version suits plants that already return pilot oil separately, because the return is routed externally. Weight 19.96 kg, NBR seals for HL fluid.
