Proportional Directional Valve 4WRZE25E325-7X/6EG24N9EK31/A1M - Bosch Rexroth R901004386

The change from rapid traverse into the controlled force phase decides both cycle time and tool life. For that transition the 4WRZE25 with spool symbol E offers 325 l/min nominal flow at 350 bar and processes the ±10 V voltage command directly at the valve.

Benefits

• 325 l/min nominal flow keeps the rapid stroke short, with up to 870 l/min available.
• ±10 V command with sign for both directions of travel.
• Internal pilot supply and external return keep the pilot stage clear of tank back pressure.
• 350 bar operating pressure gives force reserve on a small piston area.
• On-board electronics, 24 VDC supply, 7-pole connector (6 + PE).

Applications

The valve is used on forming presses, deep drawing lines and test machines with a force controlled phase. Four ports and three switching positions provide the standard size 25 function. At 20.12 kg it can still be aligned by hand, though a lifting aid helps for overhead mounting.
