Proportional Directional Valve 4WRKE25E350L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R900747226

In harsh surroundings both extra fittings and a sensitive voltage signal are a risk. The 4WRKE25E350L-3X/6EG24ETK31/F1D3M avoids both: pilot oil stays internal, the setpoint arrives as 4...20 mA, and nominal flow reaches 350 l/min.

Key benefits

• A 4...20 mA setpoint is insensitive to voltage drop and to interference picked up along the cable.
• Pilot supply and pilot return internal, no additional pilot ports on the manifold.
• 350 l/min nominal flow in size 25, maximum flow 870 l/min.
• Spool symbol E, 3 switching positions, 4 ports to ISO 4401-08-08-0-05, operating pressure up to 350 bar.
• Internal spool position feedback, linear characteristic curve, 24 VDC supply.
• 18.02 kg weight, NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

Intended for main axes in foundries, rolling mills and forging presses where heat and vibration stress the wiring. The current setpoint stays unambiguous even on long trailing cables. At 350 l/min nominal flow the valve moves large cylinders within a short cycle time.
