Proportional Directional Valve 4WRZ25E325-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900948084

A fast axis needs plenty of oil, yet the manifold should stay lean. The 4WRZ25E325-7X/6EG24N9ETK4/D3V unites both by metering 325 l/min of rated flow and supplying and returning its pilot stage internally.

Benefits

• Rated flow of 325 l/min in size 25, with up to 870 l/min across the valve.
• Internal pilot oil supply and internal pilot oil return on the pilot-operated main stage.
• Spool symbol E with three switching positions across four ports.
• External electronics, command value and feedback run through the amplifier card in the cabinet.
• 20.44 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

Valves like this work on press and lifting axes with short cycle times. As pilot oil comes from the main circuit, one pump is enough for pilot stage and working circuit. The FKM seals cope with permanently warm oil.
