Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9K31/F1D3V - Bosch Rexroth R900939924

Systems with idle circulation relieve the main circuit during pauses, yet the axis must remain ready to start at any time. This 4WRZE32W8-360-7X solves that with a completely independent pilot circuit while providing 360 l/min nominal flow.

Key benefits

• External pilot oil supply and external return make the pilot stage independent of the state of the working circuit.
• 360 l/min nominal flow, with 1600 l/min permitted at 350 bar operating pressure.
• Spool symbol W8 with three switching positions and four ports, connection diagram ISO 4401-10-09-0-05.
• Integrated electronics with a 4 to 20 mA command remove the need for a control card in the cabinet.
• FKM seals and a valve mass of 44.32 kg for continuous duty with warm HL oil.

Applications

The version suits presses and lifting axes with long idle periods in which the pump circulates without pressure. Because the control circuit is fed on its own, full pilot pressure is present the moment the working cycle starts. Concealed auxiliary actuation allows the axis to move without electrical power.
