Proportional Directional Valve 4WRKE10W6-100L-3X/6EG24K31/A1D3V - Bosch Rexroth R901123279

When the pilot stage runs on a circuit of its own, pressure dips in the main channel leave it untouched. The 4WRKE10W6-100L-3X/6EG24K31/A1D3V is arranged for that, taking pilot oil externally, draining it externally and metering 100 l/min nominal flow at up to 315 bar.

Benefits

• External pilot supply and external pilot drain, the pilot stage does not depend on main pressure
• 100 l/min nominal flow, up to 170 l/min maximum flow at 315 bar
• Spool symbol W6 with a linear characteristic curve in size 10
• On-board electronics with ±10 V command value, no extra amplifier card
• 8.37 kg, FKM seals, ISO 4401-05-05-0-05 mounting pattern

Applications

This version pays off wherever a pilot circuit with its own pump and filtration already exists, for example on large presses and test installations. The external drain also protects the pilot stage from back pressure in the shared tank line. The 100 l/min rating covers the middle range of size 10.
