Proportional Directional Valve 4WRZE25E1-325-7X/6EG24N9ETK31/A1M - Bosch Rexroth R901307658

What happens at the service ports in mid position is decided by the spool symbol, not by the controller. This version of the 4WRZE25 carries symbol E1, moves 325 l/min nominal flow and takes its command as a plus/minus 10 V voltage.

Benefits

• Spool symbol E1 in three switching positions, plus a concealed auxiliary actuation for emergency operation.
• Plus/minus 10 V command, the interface almost every axis controller offers, with no extra module.
• Nominal flow of 325 l/min and a maximum of 870 l/min at 350 bar operating pressure.
• The pilot stage is fed and drained internally, which saves two lines on the manifold.
• Mass 20.16 kg, interface pattern ISO 4401-08-08-0-05, NBR seals for hydraulic fluid HL.

Applications

It is intended for manifolds in forming plants and test rigs where the axis has to come to a defined standstill in mid position. The setpoint arrives as a voltage straight from the machine control. At 20.16 kg the valve needs a flat, ground mounting face.
