Proportional Directional Valve 4WRDE27V1-500L-6X/MXYWG/24A5 - Bosch Rexroth R901484473

When the manifold has no room for a size 32 valve but the circuit needs 500 l/min, the 4WRDE series closes the gap. The 4WRDE27V1-500L handles 500 l/min nominal flow on the ISO 4401-08-08-0-05 pattern and weighs only 20.19 kg.

Key benefits

• 500 l/min nominal flow in size 27, clearly lighter than a comparable size 32 valve.
• 20.19 kg takes load off the manifold and the piping.
• 270 bar operating pressure with NBR seals for standard HL mineral oil.
• Peak flow up to 1000 l/min leaves headroom for rapid traverse phases.
• Spool symbol V1 with three switching positions and four ports.
• On-board electronics with spool position feedback, plus minus 10 V command value on a 7-pole connector.

Applications

The type suits position-controlled axes in machines where space and weight at the manifold are limited, for instance on mobile power units or in tight machine frames. At a 270 bar design pressure the valve stays below the 350 bar class, which is enough for many standard circuits. Pilot oil is supplied and returned externally.
