Proportional Directional Valve 4WRZ32W6-360-7X/6EG24N9K4/V - Bosch Rexroth R900745118

Choosing a nominal flow below what the body allows buys resolution and costs little pressure. The 4WRZ32W6-360-7X/6EG24N9K4/V uses size 32 at 360 l/min nominal flow and works with a fully external pilot circuit.

Key benefits

• 360 l/min nominal flow in a size 32 body, maximum flow 1600 l/min.
• External pilot oil supply and external return, independent of the state of the main circuit.
• Spool symbol W6, 3 switching positions, 4 ports, connection pattern ISO 4401-10-09-0-05.
• Operating pressure up to 350 bar, FKM seals, HL hydraulic fluid.
• Concealed manual override, version without pilot pressure reducing valve.
• 43.6 kg weight, external electronics, 24 VDC supply, 3-pole connector (2 + PE).

Applications

Intended for axes in continuous duty where power loss adds up over the operating hours. The lower nominal flow of 360 l/min also improves resolution in the small signal range. A dedicated pilot circuit keeps control behaviour independent of working pressure.
