Proportional Directional Valve 4WRKE32E1-400L-3X/6EG24K31/F1D3M - Bosch Rexroth R901371893

When system pressure collapses during a load change, the pilot stage should not notice. The 4WRKE32E1-400L-3X therefore draws pilot oil from an external X port and drains it through Y while metering 400 l/min nominal flow under position control.

Benefits

• External pilot supply and external drain keep the pilot circuit apart from the main circuit.
• Nominal flow of 400 l/min, maximum flow 1550 l/min.
• Internal position feedback with a linear characteristic for repeatable spool position.
• Current command 4...20 mA on on-board electronics, supplied at 24 VDC.
• Maximum operating pressure 350 bar, connection diagram ISO 4401-10-09-0-05.
• Mass of 37 kg with NBR seals, spool symbol E1.

Technical data

Application

The valve feeds main axes on presses and testing machines whose system pressure swings widely. A separate pilot power unit or a protected branch line is required for that. Spool symbol E1 works in three switching positions across four ports.
