Proportional Directional Valve 4WRKE10E100L-3X/6EG24K31/A1D3V - Bosch Rexroth R900702018

In plants with a central pilot oil network every valve pilot stage is fed from the same source. The 4WRKE10E100L-3X/6EG24K31/A1D3V fits in there because pilot supply and pilot drain are both routed to the outside, at 100 l/min nominal flow and 315 bar operating pressure.

Benefits

• Pilot oil in and out externally, matched to a central pilot circuit
• 100 l/min nominal flow, headroom up to 170 l/min maximum flow
• Internal spool position feedback with on-board electronics and a ±10 V command value
• Spool symbol E, size 10 on the ISO 4401-05-05-0-05 pattern
• 315 bar, 8.37 kg, FKM seals, HL hydraulic fluid

Applications

This version is used in plants where a dedicated pilot pump supplies several valve blocks at constant pilot pressure. The external drain keeps the pilot stage clear of pressure peaks in the main return. Mechanically the valve is identical to the versions with internal pilot routing.
