Proportional Directional Valve 4WRZE25E325-7X/6EG24N9K31/F1D3V - Bosch Rexroth R901034025

The spool governs how the axis behaves in mid position, which makes it the first selection criterion. In this size 25 valve, symbol E works with 325 l/min nominal flow and a fully external pilot circuit.

Benefits

• Spool symbol E with three switching positions and four ports
• 325 l/min nominal flow against a valve maximum of 870 l/min
• External pilot feed and pilot return keep control behaviour independent of operating pressure up to 350 bar
• 4-20 mA interface, robust even over long cable routes
• Mass 20.62 kg, subplate mounting to ISO 4401-08-08-0-05

Application

The version is used in forming machines and hydraulic test rigs whose control loop assumes a defined mid position. An external pilot circuit lets several such valves run from one commonly protected pilot oil supply. FKM seals are fitted for HL hydraulic fluid.
