Proportional Directional Valve 4WRKE27W8-500L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901097952

The 4WRKE27W8-500L-3X/6EG24EK31/F1D3M takes pilot oil internally and returns it to tank through a dedicated Y line. That keeps the pilot stage clear of the return level in the main circuit. Spool symbol W8 passes 500 l/min nominal flow, 1000 l/min maximum, at operating pressures to 270 bar.

Benefits

• External pilot return through Y, independent of the level in the tank line.
• Internal pilot supply, so no separate feed line is needed.
• Spool symbol W8 with a linear curve and 500 l/min nominal flow.
• 4...20 mA command input, operating pressure to 270 bar, 1000 l/min maximum.
• NBR seals, 19.52 kg, mounting pattern ISO 4401-08-08-0-05.

Application

Typical plants are press lines and test rigs with several consumers working in parallel on one shared return manifold. Mineral oil of class HL is the intended fluid. Control runs through a 7-pole plug to EN 175201-804.
