Proportional Directional Valve 4WRKE27E1-500L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R901051417
Spool symbol E1 decides how the control edges of this 500 l/min valve open. In size 27 it passes 500 l/min nominal flow, takes a ±10 V command and routes its pilot oil entirely inside the valve, so no X and Y lines are needed.

Description
The 4WRKE27E1-500L-3X/6EG24ETK31/A1D3M combines the E1 spool with the simplest piping in this series. Pilot supply and return stay internal, so only the four main ports appear at the block. The curve is linear, nominal flow is 500 l/min and the peak reaches 1000 l/min at up to 270 bar.
Benefits
- Spool symbol E1 with a linear curve, three switching positions, four ports.
- Internal pilot supply and internal return, no X and Y line needed.
- Nominal flow 500 l/min, maximum 1000 l/min, operating pressure to 270 bar.
- ±10 V command straight at the on-board electronics with closed loop spool control.
- NBR seals, 19.38 kg, mounting pattern ISO 4401-08-08-0-05.
Application
The valve drives large cylinders in presses, testing machines and forming plants. Mineral oil of class HL is intended. Electrical connection is a 7-pole plug to EN 175201-804 on a 24 VDC supply.
