Proportional Directional Valve 4WRKE10W6-100L-3X/6EG24EK31/A1D3V - Bosch Rexroth R901072886
Where the tank line carries back pressure, the pilot drain belongs outside. The EK31 version of the 4WRKE10W6-100L takes pilot oil internally and drains it through a line of its own. It meters 100 l/min nominal flow at up to 315 bar operating pressure.

Description
Back pressure in a shared tank line shifts the working point of the pilot stage. The 4WRKE10W6-100L-3X/6EG24EK31/A1D3V answers that with an internal pilot supply and a dedicated external pilot drain, at 100 l/min nominal flow and 315 bar operating pressure.
Benefits
- External pilot drain, pilot pressure stays clear of back pressure in the tank line
- Internal pilot supply, one feed line fewer on the manifold
- 100 l/min nominal flow with spool symbol W6 in size 10
- 315 bar operating pressure, 170 l/min maximum flow as the upper limit
- ±10 V command value, 24 VDC, 8.39 kg, FKM seals for HL hydraulic fluid
Applications
This pilot arrangement is chosen when several pilot-operated valves share one tank line and produce noticeable return pressure there. Presses, plate shears and clamping systems with many axes switching at once are typical cases. The separate drain line carries pilot oil to tank without pressure.
Manufacturer
