Proportional Directional Valve 4WRKE25W6-350P-3X/6EG24K31/F1D3M - Bosch Rexroth R901047148

In this version both pilot oil supply and pilot oil return sit outside the main circuit, so pilot control keeps working when system pressure collapses. Nominal flow is 350 l/min, command value 4...20 mA and operating pressure up to 350 bar.

Advantages

• External pilot oil supply and external return, independent of the main circuit
• Nominal flow 350 l/min, maximum flow up to 870 l/min
• Command value 4...20 mA, stable over long cable runs
• Symbol W6, three switching positions, connection diagram ISO 4401-08-08-0-05
• Linear characteristic curve with fine control range, on-board electronics on 24 VDC
• Operating pressure up to 350 bar, 17.86 kg, NBR seals

Technical data

Applications

Used in circuits with strongly varying pressure, for example accumulator systems or variable pumps at zero stroke. A small pilot power unit then feeds the valve separately. Symbol W6 opens the actuator ports in mid position.
