Proportional Directional Valve 4WRDE25V220L-6X/VXYWG/24A1 - Bosch Rexroth R901517859

An oversized valve costs resolution on the command value. This build therefore sets 220 l/min nominal flow in size 25 while keeping the 870 l/min flow ceiling and 350 bar operating pressure. Spool symbol V works with internal position feedback of the main spool against the on-board electronics.

Key benefits

• 220 l/min nominal flow in size 25, the smaller rating of the 4WRDE range
• Spool symbol V with 3 switching positions and 4 ports
• Internal spool position feedback with on-board electronics, no external amplifier needed
• 350 bar maximum operating pressure, flow ceiling 870 l/min
• Command value ±10 V, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804
• 17.5 kg weight, FKM seals, connection diagram ISO 4401-08-08-0-05

Applications

Fits test rigs and mid-size positioning axes where a cylinder tracks a reference profile and the piston area does not call for 350 l/min. External pilot oil supply and external pilot oil return separate the pilot stage from the working circuit. Subplate mounting to ISO 4401-08-08-0-05 is interchangeable with the larger ratings of the same size.
