Proportional Directional Valve 4WRKE27W8-500L-3X/6EG24K31/A1D3M - Bosch Rexroth R900750794

The 4WRKE27W8-500L-3X/6EG24K31/A1D3M routes pilot supply and return through their own ports, which makes fault finding on large valve blocks easier. The pilot level is available at a measurable point and the return is decoupled from the tank line. Spool symbol W8 opens linearly at 500 l/min nominal flow, with 1000 l/min at peak and 270 bar.

Benefits

• Separate X and Y ports, so the pilot level can be measured during commissioning.
• Spool symbol W8 with a linear curve and 500 l/min nominal flow.
• Peak flow to 1000 l/min, operating pressure to 270 bar.
• On-board electronics with a ±10 V command and closed loop spool control.
• NBR seals, 19.3 kg, mounting pattern ISO 4401-08-08-0-05.
