Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900973424

The 520 l/min stage brings short cycle times on large cylinders. Because pilot supply and return run internally, only four ports need piping. Operating pressure reaches 350 bar.

Advantages

• Nominal flow 520 l/min, maximum flow up to 1600 l/min
• Internal pilot oil supply and internal return, no additional lines
• Symbol W6 relieves cylinder and lines in mid position
• Pressure reducing valve in the pilot stage, concealed auxiliary actuation
• External amplifier electronics, 24 VDC supply, connection diagram ISO 4401-10-09-0-05
• FKM seals for HL hydraulic fluid, operating pressure up to 350 bar, 43.7 kg

Applications

Typical for rapid-traverse axes on large presses and forging lines where cycle time counts. The amplifier card in the cabinet sets ramps and gain. The subplate interface follows ISO 4401-10-09-0-05.
