Proportional Directional Valve 4WRKE16W6-220L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901521925
The injection axis of a moulding machine repeats the same travel thousands of times. The 4WRKE16W6-220L follows the 4...20 mA current command value and passes 220 l/min nominal flow at up to 350 bar. Pilot oil comes in internally, the drain leaves outside.

Description
The injection axis of a moulding machine runs the same profile thousands of times and must not drift. The 4WRKE16W6-220L-3X/6EG24EK31/F1D3M follows a 4...20 mA current command value, passes 220 l/min nominal flow and holds spool position through internal feedback.
Benefits
- 4...20 mA current command value, the working point survives long cable runs
- 220 l/min nominal flow, maximum flow 460 l/min
- Internal pilot supply with external drain, tank line back pressure does not act on the pilot stage
- 350 bar operating pressure at 10.98 kg
- Spool symbol W6, NBR seals, 24 VDC, size 16
Applications
The valve serves injection and clamping axes on plastics machinery as well as cycled feed drives. Internal position feedback keeps repeat accuracy stable over long production runs. The standardised ISO 4401-07-07-0-05 interface allows replacement without manifold changes.
Manufacturer
Bosch Rexroth, material number R901521925, type code 4WRKE16W6-220L-3X/6EG24EK31/F1D3M. EK31 denotes internal supply with external drain of the pilot oil, F1D3M the current interface.
