Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R900768664

Where pilot oil should come from a separate filtered circuit, this version with external pilot oil supply and internal pilot return fits. Its W6 spool handles a nominal flow of 325 l/min, and up to 870 l/min can pass through the valve.

Benefits

• Nominal flow 325 l/min, roughly half as much again as the 220 l/min version of the same series
• External pilot oil supply keeps pilot control stable even when main pressure fluctuates
• Command value ±10 V processed directly by the on-board electronics
• Operating pressure 350 bar, flow through the valve up to 870 l/min
• Four ports and three switching positions to port pattern ISO 4401-08-08-0-05
• Weight 20.56 kg in a steel body sealed with NBR

Technical data

Application

This version suits installations in which several valves share one pilot supply, such as hydraulic power units in rolling mills or press lines. The internal pilot return saves a line back to the tank. HL hydraulic fluid is fed through a size 25 subplate.
