Proportional Directional Valve 4WRTE25E350P-4X/6EG24TK31/F1M - Bosch Rexroth R901443449

Some manifolds offer a pilot pressure source of their own but no free drain line. This version with fine control range matches that layout and transfers 350 l/min nominal flow at 350 bar in size 25.

Benefits

• External pilot oil supply with internal return, no dedicated drain line required.
• Linear characteristic curve with fine control range for smooth start and braking ramps.
• 350 l/min nominal flow at 350 bar, flow up to 870 l/min.
• Spool symbol E, 3 switching positions, 4 to 20 mA command value.
• 18 kg installed weight, NBR seals, connector 7-pole (6 + PE) to EN 175201-804.

Applications

Fits loading and infeed axes in presses, saw feeds and lifting gear with changing loads. The separate pilot pressure source protects the pilot stage when main pressure drops between cycles. Connection diagram ISO 4401-08-08-0-05.
