Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9K31/F1M - Bosch Rexroth R901072128

On outdoor plants there are often dozens of metres of cable between the control cabinet and the valve block. This size 32 variant therefore relies on a 4 to 20 mA current command and controls 360 l/min nominal flow at up to 350 bar.

Key benefits

• Current command value 4 to 20 mA, so cable length and voltage drop leave the setpoint untouched
• 360 l/min nominal flow, size 32 body rated to 1600 l/min
• External pilot oil supply and external return, independent of working pressure up to 350 bar
• Spool symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-10-09-0-05
• 24 V DC supply, 7-pole connector (6 + PE), weight 43.9 kg

Applications

Intended for water engineering, lock gates and other outdoor plants with long cable routes. It also makes sense in rolling mills with heavy electrical interference. The external pilot circuit has to be live before the axis is released.
