Proportional Directional Valve 4WRDE25V1-350P-6X/MXY/24F1 - Bosch Rexroth R901552167

A linear spool with a fine control range solves the starting problem: small command values produce small, easily metered oil quantities. This size 25 valve does exactly that while carrying 350 l/min nominal flow at up to 350 bar.

Key benefits

• Spool symbol V1, linear with a fine control range so motion can be metered from standstill
• Current command value 4 to 20 mA, with no signal loss over long cables
• Internal spool position feedback into the on-board electronics, 24 V DC supply
• 350 l/min nominal flow at 350 bar, with flow up to 870 l/min
• Mounting pattern ISO 4401-08-08-0-05, 4 ports, 3 switching positions, 17.5 kg

Applications

In demand on feeds that must start from rest without a jolt, on saws, presses and testing machines. The fine control range helps most with small cylinders running off a large power unit. The pilot stage is supplied and relieved externally.
