Proportional Directional Valve 4WRZ32E360-7X/6EG24N9TK4/D3M - Bosch Rexroth R901208346

The solenoid of a pilot stage works inside a narrow pressure window, while the main channel runs up to 350 bar. The 4WRZ32E360-7X/6EG24N9TK4/D3M therefore places a pressure reducing valve ahead of it, draws pilot oil externally and returns it internally, at 360 l/min nominal flow.

Benefits

• Pressure reducing valve in the pilot circuit, the pilot stage stays inside its pressure window even at 350 bar in the main channel.
• 360 l/min nominal flow, throughput up to 1600 l/min across 4 ports in size 32.
• External pilot oil supply, internal return, pilot pressure stays independent of the load pressure on the axis.
• Spool symbol E, 3 switching positions, 43.7 kg, subplate mounting to ISO 4401-10-09-0-05.
• Concealed auxiliary actuation, for setup mode and checks without electronics.

Applications

The valve serves main axes of presses and forming lines that work in the upper pressure range. The built-in pressure reducing valve saves a separate valve in the manifold and keeps switching times even across the whole pressure range. An external amplifier at 24 VDC provides the command signal.
