Proportional Directional Valve 4WRZ32E1-360-7X/6EG24N9EK4/D3M - Bosch Rexroth R901044135

When an axis pushes several hundred litres per minute back to tank, the return is rarely free of pressure. The 4WRZ32E1-360-7X/6EG24N9EK4/D3M therefore uses an external pilot oil return and works with a 360 l/min nominal flow.

Advantages

• External pilot oil return keeps the pilot circuit separate from return pressure.
• Internal pilot oil supply from P, no separate pressure line required.
• Nominal flow of 360 l/min, up to 1600 l/min total, operating pressure up to 350 bar.
• Pressure reducing valve in the pilot stage for constant pilot pressure.
• Spool symbol E1, three switching positions, connection diagram ISO 4401-10-09-0-05.
• Weight of 44 kg, NBR seals, concealed manual override.

Technical data

Applications

The valve is intended for main axes with large return volumes, for example on presses and rolling stands. A separate return prevents tank back pressure from acting on the pilot stage. Control is provided by external amplifier electronics.
