Proportional Directional Valve 4WRDE10V50L-6X/MXY/24A1 - Bosch Rexroth R901556954

If working pressure sags at the moment of start-up, an internally fed pilot stage lacks force just when it matters. The 4WRDE10V50L-6X/MXY/24A1 therefore takes pilot oil from outside through ports X and Y and provides 50 l/min nominal flow at up to 350 bar.

Benefits

• External pilot oil supply and external return operate independently of working pressure.
• 50 l/min nominal flow in size 10 on the ISO 4401-05-05-0-05 mounting pattern.
• Spool symbol V with 3 switching positions and internal spool position feedback.
• Plus or minus 10 V command into on-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals for HL fluid, weight 7.5 kg.

Applications

The version pays off on axes with strongly varying load such as tilting units, ejectors and lift platforms. As long as pilot supply is present, control keeps working even when working pressure drops away. Range maximum flow reaches 170 l/min.
