In a particle board press many cylinders share one power unit. The 4WRZE25W8-325-7X/6EG24N9TK31/F1D3M carries 325 l/min nominal flow of that, takes pilot oil from outside, returns it internally and is commanded with 4 to 20 mA.

Press lines with many cylinders working in parallel need valves that split the flow cleanly. The 4WRZE25W8-325-7X/6EG24N9TK31/F1D3M handles 325 l/min nominal flow with spool symbol W8, feeds its pilot stage from outside and returns pilot oil internally.
Benefits
- External pilot oil supply decouples control from fluctuating press pressure.
- Nominal flow 325 l/min per valve, up to 870 l/min maximum flow for the series.
- Spool symbol W8 with 3 switching positions secures behaviour while press force is held.
- Current command 4 to 20 mA for long cable runs along the press.
- ISO 4401-08-08-0-05, 350 bar operating pressure, 4 ports, weight 20.58 kg.
- Concealed manual override and UKCA conformity to SI2016/1091.

Applications
The valve works in multi-daylight presses, calibrating presses and gluing lines of the wood panel industry. External pilot supply keeps pilot pressure stable while press force changes. The internal return saves one more line at the valve.
Manufacturer
Bosch Rexroth, material number R901155725. The basis is datasheet RE 29115 for the pilot-operated proportional directional valve, together with the overview RE 07600-B.
