Proportional Directional Valve 4WRZE10E1-50-7X/6EG24N9K31/A1M - Bosch Rexroth R901037553

Die casting machines need an axis whose pilot pressure stays stable at the moment of the shot. The 4WRZE10E1-50-7X/6EG24N9K31/A1M therefore draws pilot oil and return from separate lines, regulates 50 l/min nominal flow through spool symbol E1 and is driven by an analog ±10 V signal.

Benefits

• External pilot oil supply and external return give a steady pilot pressure during pressure peaks.
• Spool symbol E1 with three switching positions and 50 l/min nominal flow.
• Version without pressure reducing valve, concealed auxiliary actuation on the pilot valve.
• Operating pressure up to 315 bar, maximum flow 170 l/min, size 10.
• Analog ±10 V command value, supply voltage 24 VDC, weight 8.48 kg.

Applications

Die casting, gravity casting and forging automats create short, hard pressure peaks in the main circuit. A separate pilot circuit keeps the pilot stage out of them. Through the subplate mounting to ISO 4401-05-05-0-05 the valve sits in the standard size 10 port pattern.
