Proportional Directional Valve 4WRKE16E220L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901499046
Some plants feed pilot oil from a separate circuit but return it internally to tank. The TK31 version of the 4WRKE16E220L is built for exactly that case. It passes 220 l/min nominal flow at 350 bar and follows a 4...20 mA current command value.

Description
Some plants supply pilot oil from a circuit of their own yet return it internally to tank. The 4WRKE16E220L-3X/6EG24TK31/F1D3M mirrors that split, at 220 l/min nominal flow, 350 bar operating pressure and a 4...20 mA command value.
Benefits
- External pilot supply, internal pilot drain, only one line has to be routed
- 220 l/min nominal flow in size 16, up to 460 l/min maximum flow
- 4...20 mA current command value at the on-board electronics
- 350 bar operating pressure, 11.28 kg, ISO 4401-07-07-0-05 pattern
- Spool symbol E, NBR seals, supplied with 24 VDC
Applications
This variant is used when pilot pressure comes from a filtered auxiliary circuit while the tank line is quiet enough for an internal drain. Compared with the fully external version it saves one pipe run. Before swapping against EK31 or K31, check the pilot port arrangement on the manifold.
Manufacturer
Bosch Rexroth, material number R901499046, type code 4WRKE16E220L-3X/6EG24TK31/F1D3M. TK31 marks the external supply combined with an internal drain of the pilot oil.
