Proportional Directional Valve 4WRDE25V1-220L-6X/VXY/24F1 - Bosch Rexroth R901550245

Seal materials decide which oil a plant may run. The 4WRDE25V1-220L-6X/VXY/24F1 is built with FKM seals, which places it differently from the NBR versions of the same series. It controls a nominal flow of 220 l/min at 350 bar operating pressure and senses spool position internally.

Key benefits

• FKM seals - a material choice for plants where NBR is not specified.
• Internal position feedback - the spool runs in a closed loop and the characteristic is linear.
• 220 l/min nominal flow in size 25 - up to 870 l/min is possible by valve size.
• 17.04 kg valve weight - clearly easier to handle than comparable size 32 valves.
• Command value 4...20 mA, supply 24 VDC - on-board electronics on a 7-pole connector (6 + PE) to EN 175201-804.
• Interface ISO 4401-08-08-0-05 - size 25 subplate mounting with 4 ports and 3 switching positions.

Technical data

Applications

The valve fits manifolds in the medium power class, for example on test rigs, injection moulding machines and handling axes with accurate travel commands. Pilot oil is supplied and drained externally, so ports X and Y have to be provided in the manifold. Spool symbol V1 and the FKM build should be checked together when ordering a replacement.

Manufacturer
