Proportional Directional Valve 4WRTE32W8-400L-4X/6EG24K31/A1M - Bosch Rexroth R900979382

Many established analogue cards issue their command value as a voltage of plus or minus 10 V. The 4WRTE32W8-400L-4X/6EG24K31/A1M accepts that signal directly at its on-board electronics and turns it into a nominal flow of 400 l/min, at operating pressures up to 350 bar with spool symbol W8.

Benefits

• A command value of plus or minus 10 V works with existing analogue outputs without an interposed card.
• Nominal flow of 400 l/min within a maximum of 1600 l/min suits mid-size cylinders in size 32.
• External pilot oil supply and external return keep the control circuit independent of the 350 bar main pressure.
• 3 switching positions across 4 ports to mounting pattern ISO 4401-10-09-0-05.
• 24 VDC at a 7-pole connector (6 + PE) to EN 175201-804, weight 37.22 kg.

Applications

The valve belongs in power units of presses, lifting gear and test rigs that already have their own filtered pilot circuit. Because pilot oil arrives separately, switching behaviour stays the same even when pressure in the main circuit swings. The medium is mineral oil of class HL, sealed with NBR.
