Proportional Directional Valve 4WRZE25W6-220-7X/6EG24K31/F1M - Bosch Rexroth R901479296

A second pressure reducing valve in the pilot stage adds nothing when the plant already regulates its pilot pressure. This version therefore does without one and transfers 220 l/min nominal flow at 350 bar.

Benefits

• Without a built-in pressure reducing valve, matched to plants with an already regulated pilot pressure.
• 220 l/min nominal flow at 350 bar, flow up to 870 l/min in size 25.
• External pilot oil supply and external return for a self-contained pilot circuit.
• 4 to 20 mA command value on the on-board electronics, internal spool position feedback.
• Spool symbol W6, 20.58 kg, UKCA declaration for electromagnetic compatibility.

Applications

Used in press lines, rolling mills and test rigs that regulate their pilot pressure centrally. Leaving out the internal pressure reducing valve cuts the number of parts in the pilot stage. Connection diagram ISO 4401-08-08-0-05.
