Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9K31/A1M - Bosch Rexroth R900970338

High back pressure in the tank line shifts the null position of an internally drained pilot stage. This variant avoids that, because pilot oil comes from outside and is also returned externally, at 325 l/min nominal flow and 350 bar operating pressure.

Benefits

• Fully external pilot routing decouples the pilot stage from tank back pressure in the working circuit.
• 325 l/min nominal flow, up to 870 l/min maximum flow.
• ±10 V voltage command processed by the electronics directly on the valve.
• 350 bar operating pressure, NBR seals for HL hydraulic fluid.
• 20.1 kg on the ISO 4401-08-08-0-05 interface.

Applications

The version makes sense on systems with long shared return lines or with return filters that build noticeable back pressure. Foundry presses, hydraulic stations with several consumers and test fields belong to this group. UKCA conformity with evidence for electromagnetic compatibility is documented.
