Proportional Directional Valve 4WRKE27W8-500L-3X/6EG24ETK31/F1D3V - Bosch Rexroth R901250339

Four main ports, one cable and still 500 l/min: the 4WRKE27W8-500L-3X/6EG24ETK31/F1D3V routes its pilot oil entirely inside, both feed and return. The symmetrical spool of symbol W8 works at operating pressures up to 270 bar.

Benefits

• Fully internal pilot routing means neither a feed nor a return line has to be laid.
• Spool symbol W8 gives the same cross section in both flow directions across 3 switching positions.
• 500 l/min nominal flow with a linear characteristic curve in size 27.
• A 4...20 mA command into on-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals for HL fluid, mounting pattern ISO 4401-08-08-0-05, 19.36 kg.

Technical data

Applications

The design suits compact control blocks on motor drives, reels and through-rod cylinders where no room is left for extra pilot lines. Because pilot feed and return sit inside, the tank line should stay as free of back pressure as possible. Range maximum flow amounts to 1000 l/min.
