Proportional Directional Valve 4WRKE25W6-220P-3X/6EG24EK31/F1D3M - Bosch Rexroth R901354998

Where back pressure builds in the tank line, the pilot oil return belongs in a separate line. That is how this size 25 valve is built: internal supply, external return, 220 l/min nominal flow and a 4...20 mA current command value at up to 350 bar.

Advantages

• External pilot oil return keeps pilot control clear of back pressure in port T
• Nominal flow 220 l/min, maximum flow up to 870 l/min
• Symbol W6 opens all four ports in mid position
• Command value 4...20 mA, on-board electronics on 24 VDC, 7-pole connector to EN 175201-804
• Linear characteristic curve with fine control range, operating pressure up to 350 bar
• 18.18 kg, connection diagram ISO 4401-08-08-0-05, NBR seals

Applications

A good match for systems with long return lines or return filters that leave several bar in port T. Symbol W6 relieves the actuator at standstill. Typical installations are presses and power units with several consumers on a shared return manifold.
