Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901032997

In stage engineering every roughness at start-up becomes visible on the platform above. The 4WRZE25W8-325-7X/6EG24N9TK31/A1D3M therefore meters 325 l/min nominal flow under position control, fed from an external pilot circuit with internal return.

Benefits

• A ±10 V command value allows soft ramps straight from the stage control.
• Nominal flow of 325 l/min moves large lifting cylinders in steady travel.
• External pilot oil supply keeps pilot pressure independent of the load on the platform.
• Spool symbol W8 with 3 switching positions secures behaviour at standstill.
• Operating pressure up to 350 bar, ISO 4401-08-08-0-05, 4 ports, weight 20.7 kg.
• UKCA to SI2016/1091, NBR seals, supply 24 V DC.

Applications

The valve moves stage lifts, under-stage machinery and safety curtains in event technology as well as lift tables in industry. The concealed manual override allows lowering a load if control voltage fails. The series maximum of 870 l/min leaves reserve for parallel axes.
