Proportional Directional Valve 4WRTE10V1-50L-4X/6EG24TK31/A1M - Bosch Rexroth R900972828

In the 4WRTE10V1-50L-4X/6EG24TK31/A1M a ±10 V command value sets the opening of the V1 spool. Nominal flow is 50 l/min, maximum operating pressure is 350 bar and position feedback happens inside the valve.

Advantages

• V1 spool with 50 l/min nominal flow and up to 170 l/min maximum flow
• Analog ±10 V command value at the on-board electronics
• External pilot oil supply and internal pilot oil return
• Operating pressure to 350 bar, 3 switching positions, 4 ports
• Internal piston position feedback instead of an external displacement sensor
• Weight 9.5 kg, NBR seals, ISO 4401-05-05-0-05 interface

Applications

The plate is fitted in feed and positioning axes of machine tools and special machinery whose controller works with voltage signals. A separate pilot feed keeps the pilot stage steady even when main pressure varies. NBR seals cover HL oil.
