Proportional Directional Valve 4WRZE25E325-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900969789

When a large plant starts up, the control circuit is switched on first and working pressure is built up afterwards. This version fits that order, because it draws pilot oil from outside through X and moves 325 l/min with spool symbol E in service.

Benefits

• External supply X means the pilot stage can already be positioned before pressure stands in the main channel.
• External drain Y keeps the tank channel from influencing the null point.
• Pressure reducing valve in the pilot line holds pilot pressure at a steady level.
• Nominal flow 325 l/min, operating pressure up to 350 bar, spool symbol E.
• Plus/minus 10 V command, on-board electronics on 24 VDC, mass 20.54 kg.

Applications

This start-up order is common in rolling mills, press lines and power plant hydraulics where the pilot circuit has a pump of its own. The valve can therefore be brought into a defined position before working pressure builds. Take pilot pressure range and filtration grade from the data sheet.
