Proportional Directional Valve 4WRKE16W6-220L-3X/6EG24K31/A1D3M - Bosch Rexroth R901378319

Adjusting axes in experimental plants often hang on a central pilot oil network with its own pump. The 4WRKE16W6-220L-3X/6EG24K31/A1D3M is arranged externally on both sides for that, passes 220 l/min nominal flow and processes the ±10 V command value inside the valve.

Benefits

• Pilot oil in and out externally, matched to a central pilot pump
• 220 l/min nominal flow, up to 460 l/min maximum flow in size 16
• ±10 V command value at the on-board electronics, a short signal chain to the spool
• 350 bar operating pressure at 11.22 kg
• Spool symbol W6, NBR seals, 24 VDC, ISO 4401-07-07-0-05 pattern

Applications

The valve serves adjusting and positioning axes in experimental plants, wind tunnels and special test rigs. A central pilot circuit supplies several valves at constant pressure. The 220 l/min rating covers the upper range of size 16.
