Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9EK4/D3V - Bosch Rexroth R900977346

Fast traverse on large cylinders needs the kind of flow that only size 32 provides. This proportional valve supplies 520 l/min nominal flow with spool symbol E1, takes pilot oil internally and discharges it externally, while an external amplifier sets the solenoid current.

Benefits

• 520 l/min nominal flow, up to 1600 l/min across the valve
• Spool symbol E1, three switching positions, four ports
• Internal pilot oil supply and external pilot oil return
• An integrated pressure reducing valve keeps pilot pressure stable at 350 bar operating pressure
• ISO 4401-10-09-0-05 port pattern, FKM seals, weight 43.68 kg

Applications

The valve controls rapid and pressing movements in forging presses, recycling plants and testing machines. Concealed auxiliary actuation allows the hydraulics to be checked without an electrical signal. It runs on 24 VDC at a 3-pole (2 + PE) connector.
